At some point in the past, I had installed posgresql and I can't get rid of it:

```
$ ps -A|egrep postg   232 ??        
287 ??         0:00.02 postgres: logger process                                                                                                                                                                                                                       
328 ??         0:00.09 postgres: writer process                                                                                                                                                                                                                       
335 ??         0:00.06 postgres: wal writer process                                                                                                                                                                                                                   
336 ??         0:00.03 postgres: autovacuum launcher process                                                                                                                                                                                                          
342 ??         0:00.01 postgres: stats collector process 

```

I'd like to stop it from starting up every time I boot, since `fs_usage` shows it keeps my disk occupied.

I've already tried adding `POSTGRES=-NO-` in `/etc/hostconfig`, but the processes keep spawing.

Also I've tried something I found on another post, with no luck:

```
$: locate postg|egrep plist
/Library/LaunchDaemons/com.edb.launchd.postgresql-8.4.plist
/Library/PostgreSQL/8.3/uninstall-postgresql.app/Contents/Info.plist
/Library/PostgreSQL/8.4/uninstall-postgresql.app/Contents/Info.plist
/Library/StartupItems/postgresql-8.3/StartupParameters.plist

$: sudo launchctl unload /Library/LaunchDaemons/com.edb.launchd.postgresql-8.4.plist

(restart)

```

But still postgresql processes show up :(
