Hi. I need to retrieve the primary key of a table and their value.
I tried with this
http://wiki.postgresql.org/wiki/Retrieve_primary_key_columns:
SELECT
pg_attribute.attname,
format_type(pg_attribute.atttypid, pg_attribute.atttypmod)
FROM pg_index, pg_class, pg_attribute
WHERE
pg_class.oid = 'TABLENAME'::regclass AND
indrelid = pg_class.oid AND
pg_attribute.attrelid = pg_class.oid AND
pg_attribute.attnum = any(pg_index.indkey);
But this shows indexes too.

How can I get only the primary key?
I have postgres 8.1.11.
Thanks, Alejandro.
