  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.
