Hey Josh, what about some t-shirts with this on the back and some

More to the point, why is it deemed necessary to equate PostgreSQL
with MySQL? Constantly doing that creates the image that the two are
somehow comparable products (and that PostgreSQL has an inferiority
complex).

BMW might compare its cars to Mercedes or other cars percieved to be
in the "luxury class" but it would never compare them to Ford or
Hyundai - to do so would create the impression that BMW and Hyundai
are in the same class. PostgreSQL should do the same.

I think the much more effective pitch is the dismissive one: sure, you
can get a lot done with MySQL - it will probably work fine for many
projects...Oh, but what about true transactions - are you ever going
to need those? Or bulletproof reliability? Or true MVCC? Have you
looked into the license restrictions? We just wanted you to know that
when you run into these issues in MySQL, we'll be here for you.

Meanwhile, if we want to pick a fight we should at least pick one with
a database in our own class.

LOL, good points!

OTOH, until we fix some of the problems we have been talking about in
the last week, we are kind of BETWEEN mysql and other databases.

Postgres is far better than Mysql, though, not a near cousin.

I would agree with you from a technical perspective but the reality is
the most used Open Source

I'm not sure this presents quite the right message.

A coworker made the snide remark that anyone that doesn't totally "get
it" is likely to really wonder about the notion of roasting a dolphin
over a spit.

Roasting dolphins over the fire isn't exactly politically correct, and
the only people that could "get it" as being funny are those that are
in the advocacy group.

And I thought that MySQL _wasn't_ the real competition, and that the
PostgreSQL community had higher standards and such...

(Note, I say this all as one of the politically-incorrect people that
find jokes involving furry creatures being blown up to be outrageously
funny at some weird visceral level.)

More to the point, why is it deemed necessary to equate PostgreSQL
with MySQL? Constantly doing that creates the image that the two are
somehow comparable products (and that PostgreSQL has an inferiority
complex).


I think that MySQL and Postgresql tend to occupy different problem
solution spaces. There's some overlap, but generally, I recommend MySQL
for CMS stuff, where multiple collations and built in full text indexing
are needed, and where you don't want to have to worry about tuning or
maintaining the database to get good performance. These are situations
where writes are heavily outnumbered by reads, and MySQL seems a good fit.

Postgresql is better for doing things with numbers, transactions, complex
data sets, and environments where writes make up a large portion of what
the database is doing.

Unfortunately, MySQL is busily trying to market themselves into the space
that Postgresql is so much better at, and they're doing a pretty good job
of it.

While I wouldn't wear the Elephant roasting a Dolphin TShirt to while
trying to make a "sale" of Postgresql over MySQL, I'd certainly wear it
around some of my LUG buddies, who would likely "get it".

A lot of my friends think I'm a MySQL bigot, even though when I'm
comparing MySQL to Postgresql, I'm generally pointing out one wart in
Postgresql for each one in MySQL. The lack of multiple locale support
within a single cluster, lack of an integrated vacuum method, need for
more sysadmin skill / time in maintenance and tuning, slow aggregate
performance, etc...

But often, all they're hearing are the negatives MySQL has if I'm
comparing. Why? Because they've had smoke blown up their orifices about
how great MySQL is and how it can do anything Postgresql can do now that
it has innodb tables. Why have they heard this so much? MySQL has the
budget to keep putting out press releases and paying for more people to
give speeches than Postgresql.

And MySQL doesn't fight fair in my opinion.

they still claim to have ACID compliance, an issue I've discussed with a
few of the folks from MySQL AB. To them, the C in ACID only implies fk
constraints. The fact that they ignore base type constraints (i.e. insert
8 billion into an int4 and it just sets the field to the max value an int4
can hold (2gig) and generates no error seems to not bother them.

Well, it bothers me, and it should bother their users, but they gloss
right over their own warts while pointing out ours.

To this day their crashme suite lists the maximum query size of Postgresql
as 16 Megs. I've told them many times it's not limited. Have they
changed it? No. Why? Because it looks a lot better to say MySQL has a
maximum query size of 1 meg versus 16 meg for pgsql than to admit that
it's their 1 meg versus our UNLIMITED.

While I'm not sure the TShirts are the answer, I would gladly wear one to
a LUG meeting in order to be a lightening rod for questions about pgsql.
and if it generates discussion and someone finds out they've been LIED to
by MySQL AB, all the better.
BMW might compare its cars to Mercedes or other cars percieved to be
in the "luxury class" but it would never compare them to Ford or
Hyundai - to do so would create the impression that BMW and Hyundai
are in the same class. PostgreSQL should do the same.
But we don't have the luxury of Mercedes of already owning a large chunk
of the market, and MySQL already spends a fair amount of effort targeting
us. Like it or not, many folks DO compare us to them, and will continue
to do so until they have been enlightened.
I think the much more effective pitch is the dismissive one: sure, you
can get a lot done with MySQL - it will probably work fine for many
projects...Oh, but what about true transactions - are you ever going
to need those? Or bulletproof reliability? Or true MVCC? Have you
looked into the license restrictions? We just wanted you to know that
when you run into these issues in MySQL, we'll be here for you.
I think the best response is the informed one. And the fair and level
headed one.

Sure, MySQL is a great storage subsystem for text and web content. I
wouldn't use it to run the payroll though, and here's why...
Meanwhile, if we want to pick a fight we should at least pick one with
a database in our own class.


I think MySQL is in our class in some ways, and we're in Oracle's class in
many ways. What matters is not what class we and they are in, but what
class we and they are PERCEIVED to be in. And most average users equate
us as being similar, because they don't know better. Pointing out where
each database is strong, while making it clear that Postgresql is the
heavy lifting winner is my approach, and it works quite well.

The worse thing that can happen for Postgresql is for someone to move an
application from MySQL to Postgresql if that application is better suited
to MySQL. and those applications exist. Being honest and fair will win
hearts and minds, and when they need the Saturn 4 instead of the Estes
rocket, they'll remember who to come to.

I like this analogy, though maybe you've overstretched. Perhaps:

MySQL = Estes. Put in InnoDB, and you have a D engine ... but it's
still a model rocket.

Postgres = Titan II. Can boost LEO missions or small interplanetary
probes. Never mind its ICBM heritage ;-)

Oracle = Saturn IV. Can take you to the moon ... if you can afford

I think MySQL is in our class in some ways, and we're in Oracle's class in
many ways. What matters is not what class we and they are in, but what
class we and they are PERCEIVED to be in. And most average users equate
us as being similar, because they don't know better. Pointing out where
each database is strong, while making it clear that Postgresql is the
heavy lifting winner is my approach, and it works quite well.


We can't change the perception of being in mysql's class by always
comparing ourselves to them. I think discussion that is initiated by us
should focus on comparisons to oracle,db2,informix,m$. We only need to
compare ourselves to mysql in response to other questioning us about
them, and when we do try to stick to technical considerations as much as
possible.

I like this analogy, though maybe you've overstretched. Perhaps:

MySQL = Estes. Put in InnoDB, and you have a D engine ... but it's
still a model rocket.

Postgres = Titan II. Can boost LEO missions or small interplanetary
probes. Never mind its ICBM heritage ;-)


All US (government) and Soviet/Russian rockets have ICBM roots.
Oracle = Saturn IV. Can take you to the moon ... if you can afford
the price tag.


What's a Saturn IV? Do you mean the Saturn V?

they still claim to have ACID compliance, an issue I've discussed with a

can hold (2gig) and generates no error seems to not bother them.


You mean that when they hit the limit, all other inserts have the MAX value?
That would be terrible!


Yes it would. And it's exacly how MySQL works:

lookee here:

mysql> create table test (i1 int, i2 numeric(6,2) not null);
Query OK, 0 rows affected (0.01 sec)

mysql> insert into test values (12345678901234,123456.23);
Query OK, 1 row affected (0.01 sec)

mysql> select * from test;
+------------+----------+
| i1 | i2 |
+------------+----------+
| 2147483647 | 99999.99 |
+------------+----------+
1 row in set (0.00 sec)

Hey, nice database to run payroll on, huh? Happens with innodb tables
too. So how can they logically claim the C in ACID, when the data I put
in is not the data that got inserted? What's the word to describe that
behaviour? Inconsistent. :-)

That's not the best URL, here's a better one:

http://www.space.com/news/a11_nomanmissions.html

Basically, the Saturn IV was the third stage of the Saturn V rocket if I
read that correctly, and the one that made the final boost to escape
from LEO to go to the moon. Oddly enough, it appears the stages were
named Saturn IC (first stage), II(second stage) and IV (third stage), with
no III I could see.

actually, may i suggeset

http://www.astronautix.com/lvfam/saturnv.htm

there actually was a design for a "Saturn IV" (really called a Saturn C4,
the contemporary Saturn C5 became the Saturn V, and development of the C4
was dropped) see

http://www.astronautix.com/lvfam/saturnc.htm)

this is awfully off topic, but here is a web page i've been working on
sporadically now for a couple of months that rocketheads may find
interesting:

http://www.averillpark.net/space/booster.html

I would suggest that if Tom wanted to use the rocket analogy, he might want
to compare PostgreSQL to maybe a contemporary Atlas 5 medium configuration.
the Titan II is quite old now and there's only one more launch scheduled.

cheers,

Sheesh. This is what I get for making an off-the-cuff analogy without
researching it first, I guess ;-)

For the record, I did mean Saturn V, not IV.

Roasting dolphins over the fire isn't exactly politically correct, and

in the advocacy group.
When I saw the image, I had to check at mysql.com to ensure that

Hello,

All due respect to everyone but political correctness is essentially
the living with the feeling that you are a politician.
I am not a politician, neither is Command Prompt. We are a business, we
have opinions, views and a sense of humor.
These traits may or may not be representative of other people's views,
opinions and or sense of humor. If it is not
to your liking, don't view it, and don't purchase a shirt of mug.

Personally I have no problem standing up and saying, we going to eat
you alive because in my not so humble opinion,
and my very business plan states that our purpose is insure that
PostgreSQL is the number one choice for database use
in the small to medium size business. If that means I upset some people
along the way... well I am not a politician, I don't
have to make everybody happy.

Cheers!
