Hmm, this code looks quite suspect, but I wonder if instead of (what
looks more or less like) a straight revert of cc0e7ebd304a as you
propose, a better fix wouldn't be to split get_parallel_object_list in
two: get_parallel_table_list for the DATABASE and SCHEMA cases, and
get_parallel_tabidx_list (or whatever) for the INDEX case.  In the first
case we just return a list of values, but in the latter case we also
meddle with the input list which becomes an output list ...
Sure, I'll try to do it.

best regards,
