The Right Way (tm) to do this would be something like
create temp table dates as select * from get_dates(...);
analyze dates;
... original select, but join against temp table ...
which would leave the planner armed with some stats about the range
of dates of interest.

I actually tried that but minus the analyze..... :(
Btw, congrats on whomever contributed to the bitmap scans (v8.1 I
believe)....the ability to use multiple indexes for a single table in
the same query is fantastic!!
