# $FreeBSD$
#
# Provide support for PostgreSQL (pgsql)
#
# Feature:	pgsql
# Usage:	USES=		pgsql[:version]
#
# version 	Maintainer can set versions required. You can set this to
#		[min]-[max] or min+ or -max or as an explicit version
#		(eg. 9.3-9.6 for [min]-[max], 9.5+ or 9.6-
#		for min+ and max-, 9.4 for an explicit version). Example:
#
#		    USES=pgsql:9.4		# Only use PostgreSQL 9.4
#		    USES=pgsql:9.3+		# Use PostgreSQL 9.3 or newer
#		    USES=pgsql:9.3-9.6	# Use PostgreSQL between 9.3 & 9.6
#		    USES=pgsql:9.6-		# Use any PostgreSQL up to 9.6
#		    USES=pgsql		# Use the default PostgreSQL
#
#		WANT_PGSQL=	server[:fetch] plperl plpython pltcl
#
#		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.
