Support for Limit in Update, Insert...

Would be any future support for limit in update/insert queries? so you could do something like

update table1 set col1=value1 limit 1000;

would update just the first 1000 rows in the table. I've been playing a little with the SPI and I get the SPI already has the support for limit the number of changes or elements in a query (the SPI_execute function).

Any comments?

Thanks a lot
