# 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

#
