With mysql it's possible to add a parameter "SQL_CALC_FOUND_ROWS" to the selectstatement and then after having made a query to the database with a limit clause you can fire off a second query, "SELECT found_rows() as numberofrows" to get the number of rows the query would have returned without the LIMIT-clause…
I wonder, is there any way, exept splitting the query up and make different calls to the database, to accomplish the same with postgresQL as with mysql?
Don't use LIMIT.
Open a cursor for the select, fetch the number of rows you want, if the FETCH returned that many, do a "MOVE FORWARD ALL IN <cursorname>". The number of rows skipped by the MOVE will be PQcmdTuples(result), so the rows you got from FETCH plus that number is the information you're looking for.
