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.

Hi,

Under Schema I have;

information_schema
pg_catalog
pg_toast
pg_toast_temp_1
pg_temp_1

and then public which contains the tables with data for my database.

Is there a list somewhere of the system catalog tables and examples of
querying it for administrative reasons?

You can either do it with the INFORMATION_SCHEMA, or the system
catalogs.  To see how to do it with the system catalogs, then start
psql with the -E switch and issue \dn and set search_path='schemaname'
and \d
