Hi, I tried to setup upgrade using pglogical - from 9.5 to 11. I did set it up, and after subscription, initial data sync seems to work fine, but then replication dies. In logs on subscriber, every 3 minutes I see: db=,user= LOG: background worker "pglogical apply 114610049:2875150205" (PID 28020) exited with exit code 1 On provider there are more messages. Every 3 minutes I get: LOG: replication connection authorized: user=some_user SSL enabled (protocol=TLSv1.3, cipher=TLS_AES_256_GCM_SHA384, compression=off) LOG: starting logical decoding for slot "pgl_somedb_provider_subscription" DETAIL: streaming transactions committing after 4AA0/5B43630, reading WAL from 4AA0/55743C0 LOG: logical decoding found consistent point at 4AA0/55743C0 DETAIL: There are no running transactions. LOG: could not receive data from client: Connection reset by peer LOG: unexpected EOF on standby connection And that's all. If it matters there are ~ 3000 tables in the replication set, and we don't replicate sequences (figured it will be simpler to just sync them once on switch to new server). How to debug/diagnose the problem? Best regards, depesz
