# pg_enum The `pg_enum` table contains entries matching enum types to their associated values and labels. The internal representation of a given enum value is actually the OID of its associated row in `pg_enum`. The OIDs for a particular enum type are guaranteed to be ordered in the way the type should sort, but there is no guarantee about the ordering of OIDs of unrelated enum types. | column | type | references | description | | :------------ | :------ | :-------------------- | :----------------------------------------------------------- | |`oid`| oid|| The object ID |`enumtypid`| oid |pgtype.oid| The OID of the `pg_type` entry owning this enum value |`enumsortorder`| float4 ||The sort position of this enum value within its enum type |`enumlabel`| name ||The textual label for this enum value
