Doc: minor improvement in pl/pgsql FETCH/MOVE documentation.

Explain that you can use any integer expression for the "count" in
pl/pgsql's versions of FETCH/MOVE, unlike the SQL versions which only
allow a constant.

Remove the duplicate version of this para under MOVE.  I don't see
a good reason to maintain two identical paras when we just said that
MOVE works exactly like FETCH.

Per Pavel Stehule, though I didn't use his text.
