FWIW I borrowed the message style in errdetail from log messages in ProcSleep():

(errmsg("process %d still waiting for %s on %s after %ld.%03d ms",
        MyProcPid, modename, buf.data, msecs, usecs),
 (errdetail_log_plural("Process holding the lock: %s. Wait queue: %s.",
                       "Processes holding the lock: %s. Wait queue: %s.",
                       lockHoldersNum, lock_holders_sbuf.data,
lock_waiters_sbuf.data))));

If we use the above message we might want to change other similar
messages I exemplified as well.
