# SYNOPSIS
#
# AX_LIB_POSTGRESQL([MINIMUM-VERSION])
#
# DESCRIPTION
#
# This macro provides tests of availability of PostgreSQL 'libpq'
# library of particular version or newer.
#
# AX_LIB_POSTGRESQL macro takes only one argument which is optional.
# If there is no required version passed, then macro does not run
# version test.
#
# The --with-postgresql option takes one of three possible values:
#
# no - do not check for PostgreSQL client library
#
# yes - do check for PostgreSQL library in standard locations
# (pg_config should be in the PATH)
#
# path - complete path to pg_config utility, use this option if
# pg_config can't be found in the PATH
#
# This macro calls:
#
# AC_SUBST(POSTGRESQL_CFLAGS)
# AC_SUBST(POSTGRESQL_LDFLAGS)
# AC_SUBST(POSTGRESQL_LIBS)
# AC_SUBST(POSTGRESQL_VERSION)
#
# And sets:
#
# HAVE_POSTGRESQL
#
# LAST MODIFICATION
#
# 2017-09-26 modified version detection to detect PostgreSQL 10 (Zabbix)
