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.
