I know the version of dropdb is 8.3.6.  There SHOULD be only one version
of postgres installed on this machine, but I will verify that tomorrow.
  This is a standard RHEL workstation running on a laptop.

The weird thing about this is, I've used this script on three other
machines just fine. Further, it worked on another database on this same
machine, but two others failed with this same error.

I'm instructing the user how to run the script remotely, so I don't have
eyes on what she's doing.  She says she is running it as the postgres
user.  I don't have access to her cluster, so I can't verify if the
postgres database is there, although I would expect it is as all these
machines were set up the same way.

She's offline for the day, so I'll catch up with her tomorrow and ask
her to list her databases in that cluster.

Thanks to all for the feedback.
