Answer a question

Upgraded 10.6 from 10.5 and now postgres 8.1 is whacked. To make things worse I tried installing 8.4 which I'm pretty sure just made things ten times worse. Anyhow, the exception I'm getting when I try to fire postgres up and just createuser is this:

createuser: could not connect to database postgres: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432"?

HOW do I fully get rid of postgres on my Mac so I can do a do-over?

Thanks

The problem was with the PostgreSQL account sitting on my machine.

I removed the account and proceeded with the uninstall using the instructions here:

Automatic Uninstall:

In the installation directory, there will be a uninstall-postgresql.app file. Executing (double clicking) that will uninstall the PostgreSQL installation.

Manual Uninstall:

Stop the server:

sudo /sbin/SystemStarter stop postgresql-8.3

Remove menu shortcuts:

sudo rm -rf /Applications/PostgreSQL 8.3

Remove the ini file:
```
sudo rm -rf /etc/postgres-reg.ini
```

Removing Startup Items:

sudo rm -rf /Library/StartupItems/postgresql-8.3

Remove the data and installed files:
```
sudo rm -rf /Library/PostgreSQL/8.3
```
Delete the user postgres:
```
sudo dscl . delete /users/postgres 
```
