[ADMIN] Query a list of tables
What is the SQL to do the following: 1) Return a list of all possible SCHEMA names within a database. 2) For a given SCHEMA return the list of all table names.

Re: [ADMIN] Query a list of tables
Is there a list somewhere of the system catalog tables and examples of querying it for administrative reasons? -Original Message- From: Scott Marlowe [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 23, 2008 10:02 AM To: Campbell, Lance Cc: pgsql-admin@postgresql.org Subject: Re: [ADMIN] Query a list of tables On Wed, Jul 23, 2008 at 8:56 AM, Campbell, Lance [EMAIL PROTECTED] wrote: What is the SQL to do the following: 1) Return a list of all possible SCHEMA names within a database. 2) For a given SCHEMA return the list of all table names.

Re: [ADMIN] Query a list of tables
Solution:
I found that by doing the following query you can get a list of all
schemas or namespaces:
select distinct schemaname from pg_tables where schemaname not in
('information_schema', 'pg_catalog');
In order to select all of the tables within a schema or namespace:
select tablename from pg_tables where schemaname='name_of_schema';
Thanks for the responses.

First you get to Postgresql docs, from there you get anywhere you want.
