Doc: Add Table of Contents to psql Reference Page

[David G. Johnston]

Hi!

IMO, the psql reference has too many non-standard subsections (and too much
material in each) to strictly conform to our guidelines for application
documentation.  It needs a Table of Contents of its own to improve
usability.

Attached.

David J.
