Good afternoon, I will describe a problem, all worked perfectly, then I needed uninstall postgress 8.4.10 and delete user "postgres", and then me install postgress 8.4.10 in the same directory, after this PT3 say me "Unable to create PostgreSQL database: PT3_2012_02_26_212032
Reason: Unable to login to database (template1). Reason: could not connect to server: Connection refused (0x0000274D/10061) Is the server running on host "???" and accepting TCP/IP connections on port 5432?", but If install postgress 8.4.10 in other directory that all excellent

Did you follow all of the steps in the PostgreSQL uninstall/reinstall guide? It sounds like it, if you deleted the postgres user, but if you missed something that could prevent the re-install working properly.

Another possibility is a problem with the data in the existing PostgreSQL folder. Why did you need to uninstall?
