Subject: [PATCH] Fixed #36148 -- Enabled native tuple comparison lookups on
 SQLite 3.37+ and Oracle 23.4+.

VALUES must be explicitly specified when declaring a sequence of tuples
on SQLite < 3.37 but it's not required on >= 3.37.

See sqlite/sqlite@9289f51 which addressed the last remaining issue with
IN.
