Unexpected message truncation in WaitForAllTransactionsToFinish - Mailing list pgsql-hackers

Hi,

In WaitForAllTransactionsToFinish():

```
        char        activity[64];
        int            rc;

        /* Oldest running xid is older than us, so wait */
        snprintf(activity,
                 sizeof(activity),
                 "Waiting for current transactions to finish (waiting for %u)",
                 waitforxid);
        pgstat_report_activity(STATE_RUNNING, activity);
```

The buffer is not big enough to hold the message if the 'waitforxid' is too big.

How about changing the message to this:

    "Waiting for transactions older than %u to finish"
