Hi,
"pg_ctl stop" does't work propley, if --slot option is specified when WAL is
flushed only it has switched.
These processes still continue even after the posmaster failed:pg_receivexlog,
walsender and logger.
How to reproduce:
1.Start PostgreSQL
2.Create slot
3.Specify --slot option to pg_receivexlog and start it
4.Stop PostgreSQL
Example commands for reproduce:
1.pg_ctl start
2.psql -c "select pg_create_physical_replication_slot('test');"
3.pg_receivexlog --slot='test' -D ./testdir
4.pg_ctl stop
This happen cause --slot option set a flush location to feedback messages,
but it only flush when wal has switched, so walsender wait for the WAL have
been replicated forever.
When --slot option is not specified, 'invalid' is set to flush location and it
use write location to check replication so it can stop the process propley.
So I thought set 'invalid' to flush location as well in this case, this problem
will be solved.
Does --slot option need to set flush location?
Thought?
