Subject: pgsql: Add min and max aggregates for composite types (records).
Date: Thu, 11 Jul 2024 15:51:01 +0000
Message-ID: <E1sRw4T-001GaI-4S@gemulon.postgresql.org> (raw)
Add min and max aggregates for composite types (records).
Like min/max for arrays, these are just thin wrappers around
the existing btree comparison function for records.
