Modified files:
src/backend/optimizer/plan: planner.c
src/backend/optimizer/util: clauses.c
src/backend/parser: analyze.c gram.y parse_clause.c
parse_coerce.c
src/include/parser: parse_clause.h parse_coerce.h

Log message:
Do honest transformation and preprocessing of LIMIT/OFFSET clauses,
instead of the former kluge whereby gram.y emitted already-transformed
expressions. This is needed so that Params appearing in these clauses
actually work correctly. I suppose some might claim that the side effect
of 'SELECT ... LIMIT 2+2' working is a new feature, but I say this is
a bug fix.
