Обсуждение: Data types
Hi guys, Does Postgres store all the possible column datatypes somewhere in its system tables? Like int8, int4, character varying, etc. I'm trying to write another GUI client that can list all the database objects in Postgres. Thanks.

See "System Catalogs" in the documentation; here's a link to the latest version: http://www.postgresql.org/docs/8.1/interactive/catalogs.html You might also want to check out the Information Schema, which is defined in the SQL standard. http://www.postgresql.org/docs/8.1/interactive/information-schema.html -- Michael Fuhr
Try pg_type. typname should give you what you're looking for.
