Delete hidden user

[aiwww]

Hi,
i`ve tried everything but nothing works when i try to delete de postgres user .
- first ... list de users and then viewed its profile

dscl . read /Users/postgres
AppleMetaNodeLocation: /Local/Default
NFSHomeDirectory: /Library/PostgreSQL8
PrimaryGroupID: 401
RealName:
PostgreSQL Server
RecordName: postgres
RecordType: dsRecTypeStandard:Users
UniqueID: 401
UserShell: /usr/bin/false

- so i tried ..
sudo dscl . -delete /Users/postgres

- but the user is still there ..
- then .. i installed a package to use sudo userdel .. but nothing worked

How about simply uninstalling PostgreSQL if you don't need that any more?

It happend after uninstalling postgres exactly for upgrade. I solved the problem. My user had no password (just used to press "Enter") ... after changing the password the sudo worked fine.
