Hi. There is a large (>5T) database on PostgreSQL 9.0.23. I would like to setup new WAL-shipping standby. https://www.postgresql.org/docs/9.0/warm-standby.html On my way I find unexpected issues. Here's the story, in short: 1. WAL archiving to remote archive is setup & verified 2. base backup is transferred directly to new server using pg_start_backup + rsync + pg_stop_backup. 3. recovery.conf is created 4. Server is started and consumes all the remaining WAL segments accumulated in the archive - finishing with optimistic message LOG: consistent recovery state reached at 9FC1/112BEE10. 5. When I go to postgres on the standby and try to connect system "postgres" database psql: FATAL: could not open file "global/11819": No such file or directory I guessed the OID refereds to the pg_authid, but other system tables might be affected too. What could be wrong here? Thanks!
