Here is an odd question.
If one was to upgrade Postgres to 9.4 from 9.1 using the --link option, then setup replication using pg_basebackup, would the standby server preserve the hard links with the pg_basebackup or will -D /new/destination/data/dir be a clean unlinked version?
Afterwards, if failing over to standby then failing back, would that implement a non linked version back on the primary if specifying a new data directory as well ?
