Subject: pgsql: Add planner support functions for range operators <@ and @>.
Date: Sat, 20 Jan 2024 18:58:02 +0000
Message-ID: <E1rRGXa-002KnM-1p@gemulon.postgresql.org> (raw)
Add planner support functions for range operators <@ and @>.
These support functions will transform expressions with constant
range values into direct comparisons on the range bound values,
which are frequently better-optimizable. The transformation is
skipped however if it would require double evaluation of a
volatile or expensive element expression.
Along the way, add the range opfamily OID to range typcache entries,
since load_rangetype_info has to compute that anyway and it seems
silly to duplicate the work later.
