Subject: pgsql: Add cross-type comparisons to contrib/btree_gin.
Date: Thu, 03 Jul 2025 20:30:46 +0000
Message-ID: <E1uXQZy-004ZLl-1t@gemulon.postgresql.org> (raw)
Add cross-type comparisons to contrib/btree_gin.
Extend the infrastructure in btree_gin.c to permit cross-type
operators, and add the code to support them for the int2, int4,
and int8 opclasses. (To keep this patch digestible, I left
the other datatypes for a separate patch.) This improves the
usability of btree_gin indexes by allowing them to support the
same set of queries that a regular btree index does.
