Обсуждение: pgsql: Exit from base backups when shutdown is requested

Exit from base backups when shutdown is requested

When the exit waits until the whole backup completes, it may take
a very long time.

In passing, add back an error check in the main loop so we detect
clients that disconnect much earlier if the backup is large.

Please make that the last commit in this area for next week.

I want to get a base from which to solidify the sync rep code, and
associated patches.

I'm not saying there will be a code clash, but there may be a clash of
detail or intention that will make life more difficult for testing.

Thanks,
