However I don't think it will work in my case. I currently have three
different ways of selecting records, 1. by timestamp range (as in my
initial example), 2. by records in a temp table, and 3. unrestricted.
The unrestricted example isn't an issue because a full table scan is
appropriate in that case. However the temp table one is a different
matter.
In the case of a temp table you have to ANALYZE the temp table after
filling it; otherwise the planner is working completely blind as to
what is in it. (autovacuum will not do this for you...)
Thanks for the tip. I haven't tried the temp table queries yet. They're next.
