Problemas with gram.y

Hi,

I'm trying to extend the CREATE INDEX statement with a fillfactor clause. In
Gram.y, I did this:

IndexStmt: CREATE index_opt_unique INDEX index_name ON qualified_name
access_method_clause '(' index_params ')' fillfactor_clause where_clause
{
IndexStmt *n = makeNode(IndexStmt);
n->unique = $2;
n->idxname = $4;
n->relation = $6;
n->accessMethod = $7;
n->indexParams = $9;
n->fillfactor = $11;
n->whereClause = $12;
$$ = (Node *)n;
}

And the clause:

fillfactor_clause:
FILLFACTOR IntegerOnly { $$ = makeInteger($2); }
{ $$ = 0; };

I had to add a new field into IndexStmt (unsigned int fillfactor). Everything
is fine after parsing except that I can't see the integer value. For example,
in transformIndexStmt (analyze.c), I've inspected stmt->fillfactor and I've got
a strange, obviously wrong, value (137616352) after issuing this statement:

create index ix_desc on products(description) fillfactor 7;

Is thre any statement with numeric clauses? The only one that I found was
Alter/Create Sequence, but there is an ugly list there.

Could anyone help me, please?

Thanks a lot!
