Обсуждение: Accessing Specific Schemas

I'm having trouble accessing specific schemas and wonder if maybe I
haven't installed something properly in 7.4.2. Here is what is
happening:

SELECT * FROM INFORMATION_SCHEMA.SCHEMATA;

ERROR:  parser: parse error at or near "."

This error appears when I try to access ANY specific schema. Help!

PostgreSQL 7.2.2 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.2 20020903 (Red Hat Linux 8.0.3.2-7)
(1 row)


Hmmm... Makes me think I'm accessing the wrong version of PostgreSQL. Does that sound likely?

Looks like your server doesn't have schema support at all ... what does "select version()" give you?

Sounds like you're talking to an older server that doesn't understand
schemas.  What does "select version()" return?

Certainly ... at least this is not the 7.4.2 you just installed.

Yes. You can get into problems if you have both an RPM version and a
compiled from source version on the same machine...

You may have accessed the RPM version when you thought you were
accessing the hand compiled one. Red Hat normally has some stuff on
there from earlier versions.

To check, select all packages, filtered by "postgres"rpm -qa | grep postgres

You might then want to decide to de-install the earlier version, or at
least more strongly locate the one you just compiled.
