Thank you for the response.
Remote psql client (application server) version is 9.2.16 and pg_lib_version function of DBD::Pg module returned version 80412.
Remove connection via psql client:
$ psql
psql (9.2.16, server 9.2.13)
Type "help" for help.
postgres=#
PQlibVersion function of libpq returned version 90213 at database server where 9.2.13 is running version of PostgreSQL.
Could it be caused by older still installed release at database server (see below)?
# yum list installed postgres\*

Hm.

We've fixed bugs with related symptoms in the past.

What libpq version is being used on the client side? The most recent
related bugfix I can find in the 9.2 commit history was in libpq, and
it came out in 9.2.8.
