Thread: [COMMITTERS] pgsql: Refactor merge path generation code.

Refactor merge path generation code.

This shouldn't change the set of paths that get generated in any
way, but it is preparatory work for further changes to allow a
partial path to be merge-joined witih a non-partial path to produce
a partial join path.

Dilip Kumar, with cosmetic adjustments by me.
