I have postgres running on W2K, version 8.2.1 which I am upgrading to
8.2.3 but when I run the upgrade I get an error as follows:

"The installer has encountered an unexpected error
installing this package. This may indicate a problem with
this package. The error code is 2803."

The install seemed to continue fine after this point and when I check in
psql I have 8.2.3 installed and the databases appear to be operational.

Any thoughts on what the error might have been and if I need to check
anything in particular to verify correct install?

Some googling on this (since it's a MSI error and not a pg one) shows
that it has something to do with files in use that cannot be replaced.
Normally it handles the pg files well, but try shutting down the service
before you upgrade. If you have any client services (including IIS)
running that's using the ODBC or libpq drivers, try shutting them down
as well.

Just to make sure you have all the files :)
