I have a function wrapping a (fairly complex) query. The query itself runs in about a 1/3rd of a second. When running the query as a 'RETURN QUERY' function on Postgres 8.4, the function runs in over 100 seconds, about 300 times slower. The function takes 3 input parameters: 2 dates and a boolean. The dates (in_date_from, in_date_to) are used several times in the function. When I replace the two parameters in the body of the query with, for instance date'2011-05-01' and date'2011-08-01', the function operates almost as speedily as the straight query. I would be grateful to know how to work around this date problem. As the function is rather large I have taken the liberty of posting it here: http://campbell-lange.net/media/files/fn_report_pers_leave.sql.html Rory -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
