pgsql: Include schema/table publications even with exclude options in d

Include schema/table publications even with exclude options in dump.

The current implementation inconsistently includes public schema but not
information_schema when those are specified in FOR TABLES IN SCHMEA ...
Apart from that, the current behavior for publications w.r.t exclude table
and schema (--exclude-table, --exclude-schema) option differs from what we
do at other places. We try to avoid including publications for
corresponding tables or schemas when an exclude-table or exclude-schema
option is given, unlike what we do for views using functions defined in a
particular schema or a subscription pointing to publications with their
corresponding exclude options.

I decided not to backpatch this as it leads to a behavior change and we don't
see any field report for current behavior.
