Yup, this change that was already in current is also needed:

*** src/backend/parser/gram.y.orig Mon Oct 18 23:59:35 1999
--- src/backend/parser/gram.y Mon Oct 18 23:55:18 1999
***************
*** 2768,2773 ****
--- 2768,2775 ----
/* finally attach the sort clause */
first_select->sortClause = $2;
first_select->forUpdate = $3;
+ first_select->limitOffset = nth(0, $4);
+ first_select->limitCount = nth(1, $4);
$$ = (Node *)first_select;
}
if (((SelectStmt *)$$)->forUpdate != NULL && QueryIsRule)

I have updated both current and REL6_5 branches.

regards, tom lane
