postgresql install problem - is package broken?

[adi zebic]

Postgresql server was installed on my ubuntu warty. For some reason I
do apt-get --purge remove postrgesql.... Today, I try to install
phpgroupware with postgresql support, so I'm trying to install
postgresql again, and here is the log of what 's hapening whet apt-get
install postgresql

Success. The database server should be started automatically.
If not, you can start the database server using:

    /etc/init.d/postgresql start

Check your installation... I would like, but how to find that binary
"postmater" or "psql" if not in package.
Do you have some issue about my problem...
