pgsql: Cosmetic code cleanup: fix a bunch of places that used "return - Mailing list pgsql-committers

Log Message:
-----------
Cosmetic code cleanup: fix a bunch of places that used "return (expr);"
rather than "return expr;" -- the latter style is used in most of the
tree. I kept the parentheses when they were necessary or useful because
the return expression was complex.
