I have read some ideas about installed libpq.so.4 to fix this, but I
wanted to run this specific problem by some experts before making any
changes.

It's seems library libpq.so.4
missing on your server. This can happened if you upgrade your
postgresql.

For perl use:

perl -MCPAN -e shell

and then:

install
DBD::Pg

For perl this is happened when you update your perl version or
postgresql library is missing or is not installed.
