Question

I have created a SQL SELECT to get all enums and their values in a schema:

SELECT 
    t.typname, array_agg(e.enumlabel) 
FROM pg_type t
JOIN pg_enum e ON t.oid = e.enumtypid
JOIN pg_namespace n ON t.typnamespace = n.oid
WHERE t.typtype = 'e' AND n.nspname = 'public'
GROUP BY typname

I have put the select into a view so I dont have to write it everytime I want to call it. The only thing that bothers me is that if I rename the schema or use it in another schema I have to rewrite the name of the schema manually, check line 6 of the code:

    WHERE t.typtype = 'e' AND n.nspname = 'public'

Public is hardtyped there. When selecting in postgres, is there a “global” variable saying from which schema you select? I was not able to find any.

Thanks

PS: I use postgres 8.4

The current schema can be retrieved using the function current_schema()
