Returning number of matches on a query when using limit

Hi. How would I return the number of matches found by a query, but when I
only want to return 30 of them ?
In MySQL there is a way of calling SQL_CALC_FOUND_ROWS to do this?

Is there something similiar that can be done in PostgreSQL ? Do I have to
rerun my query?
