v0.5.4b237

SQL: user-defined range types, and enum OIDs in every plan shape

A focused SQL-server release, both slices driven by the psycopg conformance gauge. CREATE TYPE ... AS RANGE brings user-defined range types end to end — catalog rows, the v3 extended protocol's binary codec path, and range operators over the new types — building on the range/multirange parameter support that shipped in the previous release. And enum result OIDs now survive every plan shape: joins, subqueries, set operations, and computed projections all report the enum's real pg_type OID in RowDescription (previously only simple scans did), with mood[]-style enum-array columns decoding correctly on the binary path.

Added

• CREATE TYPE ... AS RANGE / DROP TYPE: catalog rows, binary codecs on the extended protocol, range operators over user-defined range types.
• Enum result OIDs in RowDescription across joins, subqueries, set operations, and computed projections; enum-array (mood[]) columns on the binary path.
