Try increasing the work_mem first to see the change, that might help.

I have been running pieces of my PL function by hand and I have found that the following queries work by themselves taking less than a second to execute. getDateRange"('12/1/2005','12/1/2006') <- simply generates a date list. Doesn't even access a table SELECT * FROM mutualfd_weekday_qbid WHERE cusip='92193920' AND pkey >= '12/15/2005' AND pkey <= '12/15/2006'; But when combined as below it takes 10 seconds to execute. SELECT d1 as date, d2.data as data FROM "getDateRange"('12/1/2005','12/1/2006') d1 FULL OUTER JOIN (SELECT * FROM mutualfd_weekday_qbid WHERE cusip='92193920' AND pkey >= '12/15/2005' AND pkey <= '12/15/2006') d2 ON d1=d2.pkey; Do I need to increase the work_mem or is this possible still a ANALYZE issue?
