Add an index on pg_inherits.inhparent, and use it to avoid seqscans in
find_inheritance_children(). This is a complete no-op in databases without
any inheritance. In databases where there are just a few entries in
pg_inherits, it could conceivably be a small loss. However, in databases with
many inheritance parents, it can be a big win.
