And sorry if it sounds stupid but how can I move the > transaction log to this second disk ? 1) Install the 2nd disk. 2) With PostgreSQL shut down, copy the PGDATA/pg_xlog directory to the 2nd disk. 3) delete the old pg_xlog directory 4) Symlink or Mount the new pg_xlog directory under PGDATA as PGDATA/pg_xlog. 5) Restart Postgres.
