# $FreeBSD$
#
# Provide support for PostgreSQL (pgsql)
#
# Feature:	pgsql
# Usage:	USES=		pgsql[:version]
#
#		Maintainer can set version required.  Minimum and maximum
#		versions can be specified; e.g. 9.0-, 9.2+
#
#		WANT_PGSQL=	server[:fetch] pltcl plperl
#
#		Add PostgreSQL component dependency, using
#		WANT_PGSQL=	component[:target].
#		For the full list use make -V _USE_PGSQL_DEP
#		If no version is given (by the maintainer via the port or
#		by the user via defined variable), try to find the
#		currently installed version.  Fall back to default if
#		necessary.
