HI...

     When i executed a query using PQexec..It returned error.
     Is there any way to check this error is because of Database is down.

     like
     PGRES_EMPTY_QUERY -- The string sent to the backend was empty.
     PGRES_COMMAND_OK -- Successful completion of a command returning no
data
     PGRES_TUPLES_OK -- The query successfully executed
                etc......

     Like this is there any value which will specify the database
failure?????

Thanks in advance
