Fix NULL handling in multi-batch Parallel Hash Left Join.
Thomas Munro <tmunro@postgresql.org>
Fix NULL handling in multi-batch Parallel Hash Left Join. NULL keys in left joins were skipped when building batch files. Repair, by making the keep_nulls argument to ExecHashGetHashValue() depend on whether this is a left outer join, as we do in other paths. Bug #15475. Thinko in 1804284042e. Back-patch to 11.
