# SYNOPSIS
#
#   AX_CHECK_POSTGRES_DB
#
# DESCRIPTION
#
#   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.
