Postgres 9.2.4 : psql: symbol lookup error: psql: undefined symbol: PQconnectdbParams

Hi

Please help me

I am working on a CentOS release 6 server, I am struggling with the
environment setup. Please help.

data]# createdb -U postgres db0201

createdb: symbol lookup error: createdb: undefined symbol: PQconnectdbParams

data]# psql -U postgres -l

psql: symbol lookup error: psql: undefined symbol: PQconnectdbParams

When I try to locate version 8.4 I don’t get the rpms so I can remove them.
The server had some 8.4 installations

lib]# rpm -qa | grep postgresql

postgresql92-contrib-9.2.4-1PGDG.rhel6.x86_64

postgresql84-8.4.17-1PGDG.rhel6.x86_64

postgresql92-libs-9.2.4-1PGDG.rhel6.x86_64

postgresql84-server-8.4.17-1PGDG.rhel6.x86_64

postgresql92-server-9.2.4-1PGDG.rhel6.x86_64

postgresql84-libs-8.4.17-1PGDG.rhel6.x86_64

postgresql92-9.2.4-1PGDG.rhel6.x86_64

lib]#

[root(at)f020100 data]# rpm -e 'rpm -qa | grep post | grep 8.4'
