-----------
Simplify a couple of pg_dump and psql \d queries about index constraints
by joining to pg_constraint.conindid, instead of the former technique of
joining indirectly through pg_depend. This is much more straightforward
and probably faster as well. I had originally desisted from changing these
queries when conindid was added because I was worried about losing
performance, but if we join on conrelid as well as conindid then the index
on conrelid can be used when pg_constraint is large.
