Subject: pgsql: Change collation cache to use simplehash.h.
Date: Sun, 28 Jul 2024 19:57:56 +0000
Message-ID: <E1sYA1k-001dtO-RA@gemulon.postgresql.org> (raw)
Change collation cache to use simplehash.h.
Speeds up text comparison expressions when using a collation other
than the database default collation. Does not affect larger operations
such as ORDER BY, because the lookup is only done once.
