Re: Multiple clusters with same tablespace location

Thanks for the response Melvin.

The issue is that both clusters are using a base_backup and wal restore
from the same master database, so when they are restored, the tablespace
will already exist. Is there a way to change the tablespace location during
the recovery process?
