-# Plugin for monitor postgres connections.
-#
-# Licenced under GPL v2.
-#
-# Usage:
-#
-#       Symlink into /etc/munin/plugins/ and add the monitored
-#       database to the filename. e.g.:
-#
-#       ln -s /usr/share/munin/plugins/pg__connections \
-#         /etc/munin/plugins/pg_<databasename>_connections
-#       This should, however, be given through autoconf and suggest.
-#
-#       If required, give username, password and/or Postgresql server
-#       host through environment variables.
-#
-#       You must also activate Postgresql statistics. See
-#       http://www.postgresql.org/docs/7.4/interactive/monitoring-stats.html
-#       for how to enable this. Specifically, the following lines must
-#       exist in your postgresql.conf:
-#
-#           stats_start_collector = true
-#           stats_block_level = true
-#
-#
-# Parameters:
-#
-#       config   (required)
-#
-# Config variables:
-#
-#       dbhost     - Which database server to use. Defaults to
-#                    'localhost'.
-#       dbname     - Which database to use. Defaults to template1
-#       dbuser     - A Postgresql user account with read permission to
-#                    the given database. Defaults to
-#                    'postgres'. Anyway, Munin must be told which user
-#                    this plugin should be run as.
-#       dbpass     - The corresponding password, if
-#                    applicable. Default to undef. Remember that
-#                    pg_hba.conf must be configured accordingly.
-#
-# Magic markers
-#%# family=auto
-#%# capabilities=autoconf
