Subject: pgsql: Use pg_assume() to avoid compiler warning below exec_set_found()
Date: Wed, 09 Jul 2025 23:20:25 +0000
Message-ID: <E1uZe5R-005Ukb-1k@gemulon.postgresql.org> (raw)

Use pg_assume() to avoid compiler warning below exec_set_found()

The warning, visible when building with -O3 and a recent-ish gcc, is due to
gcc not realizing that found is a byvalue type and therefore will never be
interpreted as a varlena type.
