Subject: pgsql: Add a planner support function for numeric generate_series().
Date: Mon, 02 Dec 2024 11:39:54 +0000
Message-ID: <E1tI4mP-000jhj-Ey@gemulon.postgresql.org> (raw)
Add a planner support function for numeric generate_series().
This allows the planner to estimate the number of rows returned by
generate_series(numeric, numeric[, numeric]), when the input values
can be estimated at plan time.
