Subject: pgsql: Generalize hash and ordering support in amapi
Date: Thu, 27 Feb 2025 16:15:46 +0000
Message-ID: <[email protected]> (raw)

Generalize hash and ordering support in amapi

Stop comparing access method OID values against HASH_AM_OID and
BTREE_AM_OID, and instead check the IndexAmRoutine for an index to see
if it advertises its ability to perform the necessary ordering,
hashing, or cross-type comparing functionality.  A field amcanorder
already existed, this uses it more widely.  Fields amcanhash and
amcancrosscompare are added for the other purposes.
