Re: How to store data on an external drive

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



your tables are probably not using the new default tablespace

SET default_tablespace = new_tablespace_name
any new tables will be placed into new default tablespace by inserting TABLESPACE clause
can you put the WHOLE database on the external drive?
