FYI, some testing showed that playing around with spclocation in pg_tablespace is not recommended.
Do you happen to have more information about this? Because it would actually solve all my problems by moving the user created tablespaces out of the /data directory. But I would like more information on the subject before even thinking about it anymore. I did it a couple times for testing purposes. I modified the spclocation in pg_tablespace and then move the folder.
spclocation no longer exists in 9.3. If the database needs to know where the location is, it inspects the symlink in pg_tblspc to figure that out.
