37.60. user_defined_types #

The view user_defined_types currently contains all composite types defined in the current database. Only those types are shown that the current user has access to (by way of being the owner or having some privilege).

SQL knows about two kinds of user-defined types: structured types (also known as composite types in Postgres Pro Shardman) and distinct types (not implemented in Postgres Pro Shardman). To be future-proof, use the column user_defined_type_category to differentiate between these. Other user-defined types such as base types and enums, which are Postgres Pro Shardman extensions, are not shown here. For domains, see Section 37.23 instead.
