Обсуждение: backup database tablespace with rsync?

postgres A, db 'test', tablespace /pg/test1
postgres B, db 'test', tablespace /pg/test2

tablespace /pg/test1 only has A db 'test'
tablespace /pg/test2 only has B db 'test'

if
- A and B shut down
- /pg/test1 copied to /pg/test2
- A and B restarted

would B db 'test' be running the data that was in A db 'test'?

You can't rsync just pieces of the db.  you have to copy the whole database
