I'm wondering if it might be useful to be able to add estimated selectivity to 
a function definition for purposes of query estimation.  Currently function 
scans automatically return a flat default 1000 estimated rows.   It seems 
like the DBA ought to be able to ALTER FUNCTION and give it a row estimate 
for planning purposes.
