ct_check_postgres_db

This macro tries to find the headers and librarys for the PostgreSQL database to build client applications.

If includes are found, the variable PQINCPATH will be set. If librarys are found, the variable PQLIBPATH will be set. if no check was successful, the script exits with a error message.
