# 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_CPPFLAGS)
# AC_SUBST(POSTGRESQL_LDFLAGS)
# AC_SUBST(POSTGRESQL_LIBS)
# AC_SUBST(POSTGRESQL_VERSION)
#
# And sets:
#
# HAVE_POSTGRESQL
