I wasn't aware you could mix LIKE with explicit field declarations. Those expressions produce different results...the first creates a type within a type (nested) and the second creates a new unnested type based on the fields of the original type. The first expression creates a dependency while the second does not. This flexibility is only possible if you create types with the 'create table' statement. merlin -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
