It might help to have the structure of the table you're querying, like the
CREATE TABLE statement. Also what version of Postgres are you using?

Subject: [GENERAL] Sum of events over an interval; how?
? I have a number of records having a timestamp when something happened. I
am trying to find the number of events (records)?that happened per minute
over an hour timespan. I just cannot figure out how to do this.? Maybe
it's not possible?? Would a plpgsql function be a good idea so that the
number of front-end/back-end requests is small?? I'm looking for some
output (or maybe temp table) of:
Time??????????????? Count
2/17/2002 22:00:00??? 4
2/17/2002 22:01:00??? 7
2/17/2002 22:02:00???14
....
? Any help, even "Can't be done" is appreciated.
