+#
+# databases = < all | db1 db2 db3 > (default = all)
+# which databases to backup. should either be the word 'all' or a
+# space separated list of database names.
+# Note: when using 'all', pg_dumpall is used instead of pg_dump, which means
+# that cluster-wide data (such as users and groups) are saved.

+# compress = < yes | no > (default = yes)
+# if yes, compress the pg_dump output.

+# vsname = <vserver> (no default)
+# what vserver to operate on, only used if vserver = yes in /etc/backupninja.conf
+# if you do not specify a vsname the host will be operated on
+# Note: if operating on a vserver, $VROOTDIR will be prepended to backupdir.
