# Do not source this script (since it contains exit() calls)
# Before you can run postgresql you'll need to create the

# the trick.
#
# $ su postgres -c "initdb -D /var/lib/pgsql/data"

LOGFILE=/var/log/postgresql
DATADIR=/var/lib/pgsql/data
POSTGRES=/usr/bin/postgres

# Return values (according to LSB):
# 0 - success
# 1 - generic or unspecified error
# 2 - invalid or excess argument(s)
# 3 - unimplemented feature (e.g. "reload")
# 4 - insufficient privilege
# 5 - program is not installed
# 6 - program is not configured
# 7 - program is not running
