How to install libpq-dev on Centos 5.5

In order to develop one web application based on postgresql, i need to install libpq on my centos.

I can install it by "apt-get install libpq-dev" on ubuntu, but i can not install it on centos by "yum install libpq".

Who can tell me how to install it, thanks!

The package is called postgresql-libs on Red Hat and derived distributions.

I just had to install this on my CentOS 6 server since psycopg2 required pg_config. Boo yah:

yum install postgresql-devel

Update

If you still encounter issues with pg_config, you may need to add it to your PATH, e.g.:

export PATH=$PATH:/usr/pgsql-x.x/bin

where x.x is your version, such as /usr/pgsql-9.2./bin.

It is libpqxx:
