Hi
My box: RedHat 9.0, Pentium III
Recently I upgraded from PostgreSQL 7.3.2 to PostgreSQL 7.4.1.
The PostgreSQL 7.3.2's rpms were installed from RehHat CDs
The PostgreSQL 7.4.1's rpms I used to upgrade were downloaded from RHEL3
subdirectory (of the mirror ftp://ftp4.ar.postgresql.org/pub/mir.../redhat/rhel3).
The upgrade is working well, even I can connect to PostgreSQL from a PHP
script.
Before upgrading I used to connect to PostgresQL using pgdb.py (part of
PyGreSQL that comes with one of the rpms I guess). The sintaxis I was using
from interactive shell were:
--------------- import pgdb dbConnect = pgdb.connect(ds n='localhost:or acle', user='manuel',
password='')cursor = dbConnect.curso r() cursor.execu te("select * from address") while (1):
.... row = cursor.fetchone ()
.... if row == None:
.... break
.... print row
....
['BAILEY','WILLI AM',None,None,N one,None,'213-293-0223',None]
['ADAMS','JACK', None,None,None, None,'415-453-7330',None]
-
-cursor.close () dbConnect.cl ose()
-----------------------
As you can see, the connection and fechting were successful.
But now when I input the same sintaxis with the new Installation(Po stgreSQL
7.4.1), I get an error when I enter rhe four line:
----------------import pgdb dbConnect = pgdb.connect(ds n='localhost:or acle', user='manuel',
password='')cursor = dbConnect.curso r() cursor.execu te("select * from address")
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File "/usr/lib/python2.2/site-packages/pgdb.py", line 189, in execute
self.executeman y(operation, (params,))
File "/usr/lib/python2.2/site-packages/pgdb.py", line 221, in executemany
desc = type[1:2]+self ._cache.getdesc r(typ[2])
File "/usr/lib/python2.2/site-packages/pgdb.py", line 149, in getdescr
self ._source.execut e(
_pg.error: ERROR: non exist the column "typprtlen"
------------------
By the way the types of columns from address table are:
lastname varchar(25)
firstname varchar(25)
street varchar(30)
city varchar(15)
state varchar(2)
zip int
phone varchar(12)
ext varchar(5)
My questions:
-Anybody knows why I can't connect to PostgreSQL using the pgdb.py module
now?
- Perhaps the sintaxis has changed?

Well at CMD we only use psycopg as it is the only one we have used that
has proven to:
A. Actually be actively maintained.
B. Have a solid community behind it.
C. It is what Zope (although we don't Zope) uses.

Simply distribute the same files distributed with postgres 7.3.X, what
you did in last 7.4.1 distribution was insert a pre 7.3.2 pgdb.py
IMHO is a pity remove the pyhton subpackage just for a so little mistake.

As a user of PostgreSQL I totally agree with Gaetano Mendola.
There is no reason to pull the python subpackage out of the main set,

The decision to remove all interfaces from the main CVS tree was made in
part to remove the responsibility of the core developers to maintain the
build systems for various components and try to make sure that bugs and
new backend functionality were addressed. While this allows core
developers to focus solely on the backend it puts a lot of pressure on the
packagers to track the various components they are now distributing.
This is not the first packaging problem and it won't be the last if we
rely on a very busy package maintainer to track each independent project.
The only people who really know which version needs to go into an package
are the projects' maintainers.
Asking the interface projects to build and distribute their own packages
is not going to work because they are not likely to have all of the
requirements the existing packagers already have: expertise with the
packaging system, access to machines to build this on a variety of
platforms, and contacts with the upstream package distributors.
Perhaps a system where each project maintainer could register the correct
version of their package to go with each server version. This way in
addition to the hackers email that goes out saying "we're planning on
making the 7.X.X release on Monday" this would also go out to the project
maintainers who would then produce a new version if necessary and register
it on a website somewhere. Then when a packager is ready to produce a
package he can check the website and immediately find for all packages the
correct version of the package to distribute.
Lamar, Oliver, interface maintainers, and others would that be useful?

Hello,
I started to write my PostgreSQL layer. I tried pyPgSQL and PyGreSQL. I
made a *very minimal* performance test and comparsion with the same
thing in php. Table "movie" has 129 record and many fields.
I found PyGreSQL / DB-API / fetchall horrible slow (32 sec in my test).
PHP did 13 secs and it gave the result in associative array. Maybe I did
something bad.

Hi guys,

pgdb.zip is an addition to scite-debug, which adds source debugging to
the popular SciTE programmer's editor. gdbpy.zip is a standalone
version which can be run from Emacs.
These allow you to single-step from Python to C code in a debugger
session.

Hello group,
I've run into a small problem with pgdb which is actually not PostgreSQL
specific - I just do not understand the Python syntax at one point.
I'm trying to initialize a connection to a PG database. So help(pgdb) says:
pgdb.connect(connect_string) -connection
connect_string = 'host:database:user:password:opt:tty'
All parts are optional. You may also pass host through
