Re: [HACKERS] postgres 9.3 postgres_fdw ::LOG: could not receive data from client: Connection reset by peer
Local server log has the line and remote table log is empty (it is configured for minimum warning and when I produce one it appears in log OK) And I have new details - it happens on some additional environments - not constantly. Some hours it happens every time, then just stops appearing: postgres@hostname:~$ grep user 9.3/main/pg_log/postgresql-2016-11-22_00.log | cat -n 1 2016-11-22 06:00:02 UTC 127.0.0.1 user::LOG: could not receive data from client: Connection reset by peer 2 2016-11-22 06:00:03 UTC 127.0.0.1 user::LOG: could not receive data from client: Connection reset by peer 3 2016-11-22 06:00:03 UTC 127.0.0.1 user::LOG: could not receive data from client: Connection reset by peer 4 2016-11-22 10:06:08 UTC 127.0.0.1 user::LOG: could not receive data from client: Connection reset by peer 5 2016-11-22 10:06:08 UTC 127.0.0.1 user ::LOG: could not receive data from client: Connection reset by peer 6 2016-11-22 10:06:08 UTC 127.0.0.1 user::LOG: could not receive data from client: Connection reset by peer 7 2016-11-22 11:25:27 UTC 127.0.0.1 user::LOG: could not receive data from client: Connection reset by peer 8 2016-11-22 11:25:27 UTC 127.0.0.1 user::LOG: could not receive data from client: Connection reset by peer 9 2016-11-22 11:25:27 UTC 127.0.0.1 user::LOG: could not receive data from client: Connection reset by peer this is log from local server where user runs same bunch of three statements MINUTELY But when it start happening if I psql to db, same statement produces NOT this string in log. Here reason why you should not follow this post any more: postgres=# select version(); version -- PostgreSQL 9.3.9 on x86_64-unknown-linux-gnu, compiled by gcc (Debian 4.7.2-5) 4.7.2, 64-bit (1 row) I will just upgrade it. And this is the only machine I have this weird behavior at.

Whichever it is, is there an entry in the logfile for the other server which seems to match up to this one? That may have more useful details. Cheers, Jeff

No, I select from it OK. The bug(?) is that when I do it in oppened psql session it produces no log, and when I run same select as psql -c "SELECT..." it gives the above 2016-11-22 20:18 GMT+00:00 Robert Haas : > On Tue, Nov 22, 2016 at 5:05 AM, Vladimir Svedov > wrote: > > Hi, > > Sorry - tried to reproduce on other machine and gather all statements. > And > > failed > > Installed 9.3 (which has those symptoms) and still can't reproduce. > > Must be platform specific, not version > > Probably the foreign server isn't configured properly, and points to a > host/port to that resets the connection when you attempt to connect to > it. > > -- > Robert Haas > EnterpriseDB: http://www.enterprisedb.com > The Enterprise PostgreSQL Company >
