Hi.
IMO, I think that commit a61b1f7
<https://github.com/postgres/postgres/commit/a61b1f74823c9c4f79c95226a461f1e7a367764b>,
has an oversight.
Currently is losing the result of recursion of function
translate_col_privs_multilevel.
Once the variable result (Bitmapset pointer) is reassigned.
Without a test case for this patch.
But also, do not have a test case for the current thinko in head.
Pass regress check.
regards,
Ranier Vilela
