Thread: Getting table attributes
Dear All, I'm trying to get a table containing all the user created tables, which contains the column name and their types. Basically, I want to be able to do "\d all_user_tables" - but I can't use the \d notation. I tried to combine the pg_ tables, but I couldn't get what I wanted (due to my lack of skill). Any ideas?

this query will list every table (with its attributes) in the "public" schema. You could alter the where clause to add more schemas (maybe using IN):
SELECT
N.nspname,
C.relname,
A.attname,
pg_catalog.format_type(a.atttypid, a.atttypmod) AS typeName
FROM
pg_class C,
pg_namespace N,
pg_attribute A,
pg_type T
WHERE
(C.relkind='r') AND
(N.oid=C.relnamespace) AND
(A.attrelid=C.oid) AND
(A.atttypid=T.oid) AND
(A.attnum>0) AND
(NOT A.attisdropped) AND
(N.nspname ILIKE 'public')
ORDER BY
C.oid, A.attnum;

If you start psql with the -E flag then it'll show you the SQL query it generates for the various \commands as you run them. If you're using a recent version of postgres you can probably find the data in a more version-independent way within information_schema, but I've not played with that yet. Cheers, Steve
