+=head2 Plugin C<postgresql>
+
+The C<postgresql> plugin queries statistics from PostgreSQL databases. It
+keeps a persistent connection to all configured databases and tries to
+reconnect if the connection has been interrupted. The statistics are collected
+from PostgreSQL's B<statistics collector> which thus has to be enabled for
+this plugin to work correctly. This should usually be the case by default.
+See the section "The Statistics Collector" of the B<PostgreSQL Documentation>
+for details.

+=item B<Database> block
+
+The B<Database> block defines one PostgreSQL database for which to collect
+statistics. It accepts a single mandatory argument which specifies the
+database name. None of the other options are required. PostgreSQL will use
+default values as documented in the section "CONNECTING TO A DATABASE" in the
+L<psql(1)> manpage. However, be aware that those defaults may be influenced by
+the user collectd is run as and special environment variables. See the manpage
+for details.
+
+=item B<Host> I<hostname>
+
+Specify the hostname or IP of the PostgreSQL server to connect to. If the
+value begins with a slash, it is interpreted as the directory name in which to
+look for the UNIX domain socket.
+
+This option is also used to determine the hostname that is associated with a
+collected data set. If it has been omitted or either begins with with a slash
+or equals B<localhost> it will be replaced with the global hostname definition
+of collectd. Any other value will be passed literally to collectd when
+dispatching values. Also see the global B<Hostname> and B<FQDNLookup> options.
+
+=item B<Port> I<port>
+
+Specify the TCP port or the local UNIX domain socket file extension of the
+server.
+
+=item B<User> I<username>
+
+Specify the username to be used when connecting to the server.
+
+=item B<Password> I<password>
+
+Specify the password to be used when connecting to the server.

+=item B<SSLMode> I<disable>|I<allow>|I<prefer>|I<require>

+following modes are supported:
+

+
+=item I<disable>
+
+Do not use SSL at all.
+
+=item I<allow>

+B<PostgreSQL Documentation> for details.
+
+=item B<Service> I<service_name>
+

+=item B<ForceUseProcfs> I<true>|I<false>
+
+By default, the C<thermal> plugin tries to read the statistics from the Linux
+C<sysfs> interface. If that is not available, the plugin falls back to the
+C<procfs> interface. By setting this option to I<true>, you can force the
+plugin to use the latter. This option defaults to I<false>.

+used multiple times to specify a list of devices.

+
+Invert the selection: If set to true, all devices B<except> the ones that
+match the device names specified by the B<Device> option are collected. By
