OUTER JOIN IS SLOW

[Benjamin Arai <benjamin(at)araisoft(dot)com>]

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?
