Similar to pg_get_viewdef() and pg_get_functiondef() it would be useful with a pg_get_tabledef() to get a full description of how a table is defined.
Because there's already pg_get_viewdef(), pg_get_functiondef(), pg_get_constraintdef(), pg_indexes.indexdef and ways to get all GRANT and REVOKE privs, any pg_get_tabledef() would just be the CREATE TABLE statement without PRIMARY KEY or FOREIGN KEY clauses.
