What's the best way to create a connection with dblink with persisted
connections for web applications?
For example:
I want to have a view that links to a table in another pg database so I
can mask the connection and make it easier to query.
so I would do this ...
create view myremote_pg_pro c as
select *
from dblink('myconne ction','select proname, prosrc from pg_proc')
as t1(proname name, prosrc text);
so I can do this ...
select * from myremote_pg_pro c where proname like 'bytea%';
I understand that a connection can be made by dblink_connect( text
connstr) and
dblink_connect( text connname, text connstr), but how do you suggest
making the first connection from a web application?
select dblink('myconne ction','127.0.0 .1 port=5432 dbname=template 1
user=postgres password=mypass wd')
Do you suggestion not using the persistent connection? and do this?
create view myremote_pg_pro c as
select *
from dblink('myconne ction','127.0.0 .1 port=5432 dbname=template 1
user=postgres password=mypass wd','select proname, prosrc from pg_proc')
as t1(proname name, prosrc text);
Thanks a Bunch,
Brian

It all depends on how you intend to use the dblink connections.
If your web page connects to Postgres, issues a single query using
dblink (via a view or whatever), and then completes, you don't need a
persistent dblink connection -- just use the explicit connection syntax.
If, on the other hand, your web page connects to Postgres, issues
several queries using dblink (via a view or whatever), and then
completes, it would make sense to use a persistent dblink connection. In
that case, execute dblink_connect( ) before you execute your queries. Use
named persistent connections if you need more than one, anonymous otherwise.

Is there a way to rollback a dblink transaction?
Say, I delete some data from the remote database, but I don't want this
to be visible untill the data is inserted in the current database. And
if the insertion of data in the current database throws an error, I want
to rollback the dblink transaction, which should restore data in its
original remote location.
Thanks.

Hello all!
I am rather stuck and am hoping someone can help. I am working on a
project where users need to be able to send one query which will hit
databases on multiple hosts (the database structures are the same) and
tie the data back together again.
After doing lots of reading it looks like dblink might be a great
solution for this. After trying to insert dblink.sql into the database,
I just get a series of errors:

Hello,
we want use dblink to connect several databases in a client/server environment. Connection from local users to the remote databases should be possible only for privileged users. We tried a solution with dblink, embedding this command in a view, like this:

Hi list,
My boss would like to convert from MySQL to PostgreSQL, but there are a few
things that hold us back.
We'd like to have the databases in several physical servers, with referential
integrity between the tables. Reading from Oracle articles, their
referential integrity can be done using their dblink and triggers. What I'd
like to ask is whether contrib/dblink is stable? Seeing dblink in a contrib
directory does bring a doubt...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
