It was far stupider than that. I had been playing around with a couple of different data clusters before doing a complete reinstall of PostgreSQL. I just realized I was trying to start a cluster that I was no longer using and the postgres account didn't have appropriate permissions for. It's one of those things where once you ask the question, you realize that the answer is implicit in the question. But a useful followup question is, how do I make this start itself when Windows starts? The service is set up to run as postgres and execute "C:\Program Files\PostgreSQL\8.3\bin\pg_ctl.exe" runservice -w -N "pgsql-8.3" -D "C:\Program Files\PostgreSQL\8.3\data\" This *is* pointing to the right data cluster (which I'm able to start successfully from the command line), but it's not starting automatically (even though it's configured to) and when I try to start it manually within the Component Services Manager, it generates the following error: Error 1069: The service did not start due to a logon failure.
