I just installed a new Centos 6.3 server, upgraded the REMI repositories, and from there, installed postgresql:
yum install postgresql92 postgresql92-devel postgresql92-server postgresql92-libs postgresql92-contrib –y

after that I installed php:
yum --enablerepo=remi,remi-test install php php-common
And the PHP modules:
yum --enablerepo=remi,remi-test install php-pecl-apc php-cli php-pear php-pdo php-mysql php-pgsql php-pecl-mongo php-sqlite php-pecl-memcache php-pecl-memcached php-gd php-mbstring php-mcrypt php-xml

Started the postrgesql database:
service postgresql-9.2 start
Created a password to the postrgresq user, login via VNC, open the pgadmin, but when I tried to create a new database:

An error has ocurred:
Error connecting to the server: definition of service “postgresql-9.2” not found

And I don’t know exactly why is that happening, I’ve checked and everything seems to be installed correctly… :S
So, if someone have any idea and can point me to any direction it will be very helpful..

Ahh, something else, I was in the VNC sesión with the user :1 and suddenly pgadmin hang, so I kill the process from webmin, but after that, it dont let me login with that user, it said: Cant establish a connection since the destiny denies the connection… :S
The other user Works perfectly, but user 1 its pretty much useless… :S
Any idea about that issue can also help me a lot.

Thanks a lot for all your help.
