-\n\
-This plugin tests a PostgreSQL DBMS to determine whether it is active and\n\
-accepting queries. In its current operation, it simply connects to the\n\
-specified database, and then disconnects. If no database is specified, it\n\
-connects to the template1 database, which is present in every functioning \n\
-PostgreSQL DBMS.\n\
-\n\
-The plugin will connect to a local postmaster if no host is specified. To\n\
-connect to a remote host, be sure that the remote postmaster accepts TCP/IP\n\
-connections (start the postmaster with the -i option).\n\
-\n\
-Typically, the nagios user (unless the --logname option is used) should be\n\
-able to connect to the database without a password. The plugin can also send\n\
-a password, but no effort is made to obsure or encrypt the password.\n"
