New timeline when starting with a restored data dir
Hi,
I'm trying to set up Barman, and I've noticed that PostgreSQL 10
creates a new timeline when starting with a restored data dir.
Particularly, when WAL files are delivered via restore_command. When
WAL files are copied to pg_wal dir, no new timeline is created. Is it
to be expected? Can you explain?
I decided to ask here first, since you might know better how
PostgreSQL operates.
Thanks in advance.
It’s normal behaviour to create a new timeline, when a PostgreSQL slave become a new master. This is for what timelines were designed.
