Subject: Re: Postgresql with nextcloud in Windows Server
To: Adrian Klaver <adrian.klaver@xxxxxxxxxxx>
Thanks for your reply and I hope this answers can help your questions
1) The nextcloud is running on PostgreSQL server. Cloud system needs PostgreSQL server.
2) Nextcloud system try to connect PostgreSQL server all time.
2019-03-27 20:46:59.396 LOG: connection received: host=xxx.xxx.xxx.xxx port=xxxx
2019-03-27 20:46:59.403 LOG: connection authorized: user=user_name database=db_name
2019-03-27 20:46:59.463 LOG: disconnection: session time: 0:00:00.067 user=user_name database=db_name host=xxx.xxx.xxx.xxx port=xxxx
this connections repeat almost per 10sec.
Other clients well... use this PostgreSQL but not so much.(almost 30 people use this PostgreSQL include nextcloud system users)
3) Yes. log files doesn't shows problems clearly. I just checked log files and saw difference when server couldn't connected.
2019-03-27 20:46:59.396 LOG: connection received: host=xxx.xxx.xxx.xxx port=xxxx
2019-03-27 20:46:59.403 LOG: connection authorized: user=user_name database=db_name
this log repeated and no disconnection log.
4) After problem occur, if try to connect to windows server, windows remote access shows time-out error. PostgreSQL server also too.
5) Before the server doesn't work normally, there is no problem to use PostgreSQL (even nextcloud system, too.)
6) No, It doesn't work. PostgreSQL service status doesn't changed.
7) When I restart server, I check PostgreSQL data and I see some schema data disappeared(only data). log files says 'db system was not properly shut down' so 'automatic recover in progress' when PostgreSQL server started after Windows Server get restarted.
I think this 'not properly shut down' causes windows server cold booting.(I need to turn on the server quickly for some reason and my server spends a lot of time to restart.)

Not sure I entirely understand the above, so to help can you answer the
following:
1) The Postgres server is running on nextcloud, correct?
2) The client you are using to connect to the server is on nextcloud
also or somewhere else?
3) The log files do not show a problem, is this correct?
4) Do you see an error message on the client end when you try to connect?
5) Have you looked at your pg_hba.conf to see if allows connections from
your client?
6) Not sure what you mean when you say you cannot stop the service, but
that you can restart it?
7) How do you know that data has disappeared?
