Thread: pgsql: Reword text on ROW SHARE lock as acquired by SELECT FOR

Reword text on ROW SHARE lock as acquired by SELECT FOR <lock>

It was missing lock levels FOR KEY SHARE and FOR NO KEY EXCLUSIVE; but
also SELECT FOR UPDATE is not a command separate from SELECT, as the
original text implied.  It is clearer to state that FOR <lock strength>
is an option of regular SELECT.

Per suggestion from Joey Bodoia <jbodoia21@cmc.edu>
