Thread: pgsql: Add a test case for a316a3bc
Add a test case for a316a3bc a316a3bc fixed the code in build_simpl_rel() that propagates RelOptInfo.userid from parent to child rels so that it works correctly for the child rels of a UNION ALL subquery rel, though no tests were added in that commit. So do so here. As noted in the discussion, coming up with a test case in the core regression suite for this fix has turned out to be tricky, so the test case is added to the postgres_fdw's suite instead. postgresGetForeignRelSize()'s use of user mapping for the user specified in RelOptInfo.userid makes it relatively easier to craft a test case around.
