| 13 | * Description: | ||
| 14 | * | ||
| 15 | * This plugin attempts to connect to an PostgreSQL Server | ||
| 16 | * with the optional specified parameters db and port. | ||
| 17 | * | ||
| 18 | * The plugin returns | ||
| 19 | * STATE_OK and the Version Number of the Server when all is fine | ||
| 20 | * STATE_CRITICAL if the Connection can't be esablished | ||
| 21 | * STATE_WARNING if the connection was established but the | ||
| 22 | * program can't get the Versoin Number | ||
| 23 | * STATE_UNKNOWN if to many parameters are given | ||
