[COMMITTERS] pgsql: Tighten up some code in RelationBuildPartitionDesc.

Tighten up some code in RelationBuildPartitionDesc.

This probably doesn't save anything meaningful in terms of
performance, but making the code simpler is a good idea anyway.

Code by Beena Emerson, extracted from a larger patch by Jeevan
Ladhe, slightly adjusted by me.
