pgsql: Docs: document that psql's "\i -" means read from stdin.

Docs: document that psql's "\i -" means read from stdin.

not have known it from the documentation. Also back-patch the notes
I added to HEAD earlier today about behavior of the "-f -" switch,
which likewise have been valid for many releases.
