In pmdie(), we have the following code, which doesn't seem to make
much sense. If the state is PM_RECOVERY at the top of this section it
will get changed to PM_WAIT_BACKENDS and then to PM_WAIT_BACKENDS
again. Either the two "if" statements should be merged (and both bits
should be handled with the same block of code) or the second one
should say "else if". Or at least, I think so...
if (pmState == PM_RECOVERY)
{
/* only bgwriter is active in this state */
pmState = PM_WAIT_BACKENDS;
}
if (pmState == PM_RUN ||
pmState == PM_WAIT_BACKUP ||
pmState == PM_WAIT_READONLY ||
pmState == PM_WAIT_BACKENDS ||
pmState == PM_HOT_STANDBY)
{
ereport(LOG,
(errmsg("aborting any active transactions")));
/* shut down all backends and autovac workers */
SignalSomeChildren(SIGTERM,
BACKEND_TYPE_NORMAL |
BACKEND_TYPE_AUTOVAC); /* and the autovac launcher too
*/
if (AutoVacPID != 0)
signal_child(AutoVacPID, SIGTERM);
/* and the walwriter too */
if (WalWriterPID != 0)
signal_child(WalWriterPID, SIGTERM);
pmState = PM_WAIT_BACKENDS;
}
