Done.
can you help me in this
Yes, by suggesting you try something other then pg_sample. The last commit was 4 years ago and it does not seem to be up to date enough.
What sort of sampling do you want to do?

NAME
pg_sample - extract a small, sample dataset from a larger PostgreSQL
database while maintaining referential integrity.
=head1 SYNOPSIS
pg_sample [ option... ] [ dbname ]
=head1 DESCRIPTION
pg_sample is a utility for exporting a small, sample dataset from a
larger PostgreSQL database. The output and command-line options closely
resemble the pg_dump backup utility (although only the plain-text format
is supported).
The sample database produced includes all tables from the original,
maintains referential integrity, and supports circular dependencies.
To build an actual instance of the sample database, the output of
this script
can be piped to the psql utility. For example, assuming we have an
existing
PostgreSQL database named "mydb", a sample database could be
constructed with:
createdb sampledb
pg_sample mydb | psql sampledb
and so on .......

Also do a "yum search perl-" and you should find most, if not
all what you need natively packaged for your particular Linux
distro. You're better off just sticking with the pre-packaged
perl modules unless you specifically need something special.
You'll find more modules if you also enable the EPEL yum repo by
setting enabled=1 in the first section of
/etc/yum.repos.d/epel.conf and rerunning that yum search command.
