Hackers,
I'm curious about behavior such as this:
bric=# select generate_series('2011-05-31'::timestamp ,
'2012-04-01'::timestamp, '1 month');
generate_series

That's just how intervals that represent varying periods of time work. You
would need to write your own. But a series of end-of-month dates is pretty
easy:

The query is marginally trickier. But the better calendaring apps give a
