Hi Carlos,
I'm guessing you want the "adminpack" for use with pgadmin.
It's usually bundled in the postgresql92-contrib RPM with EL distros.
As root install the package
# yum install postgresql92-contrib
As postgres
$ psql
postgres=# CREATE EXTENSION adminpack;
CREATE EXTENSION
You can list
I have a Amazon EC2 AMI running with PostgreSQL 9.2 installed. It
appears to be a RHEL based distribution however I need to get server
instrumentation installed on this virtual server. Does anyone know how
I can accomplish this? I don't even see a proper download for my
version of PostgreSQL 9.2.
