get_parallel_object_list() was trying to serve two masters, and it was
doing a bad job at both. In particular, it treated the given user_list
as an output argument, but only sometimes. This was confusing, and the
two paths through it didn't really have all that much in common, so the
complexity wasn't buying us much. Split it in two:
get_parallel_tables_list() handles the straightforward cases for
schemas, databases and tables, takes one list as argument and returns
another list.
A new function get_parallel_tabidx_list() handles the case for indexes.
This takes a list as argument and outputs two lists, just like
get_parallel_object_list used to do, but now the API is clearer (IMO
anyway). Another difference is that accompanying the list of indexes
now we have a list of tables as an OID list rather than a
fully-qualified table name list. This makes some comparisons easier,
and we don't really need the names of the tables, just their OIDs.
(This requires atooid, which requires <stdlib.h>).
