# PostgreSQL database rc.d control script
#
# PROVIDE: pgsql
# REQUIRE: DAEMON
# KEYWORD: shutdown
#
# You will need to set some variables in /etc/rc.conf to start PostgreSQL:
#
# pgsql=YES
#
# The following variables are optional:
#
#	pgsql_flags="-i"		# allows TCP/IP connections
#	pgsql_flags="-i -l"		# enables SSL connections
#	pgsql_home="/path/to/home"	# path to pgsql database directory
#
# "pgsql_flags" contains options for the PostgreSQL postmaster.  See
# postmaster(1) for possible options.
