So how are you moving the 9.0 directory?

Just using a mv command like below:
mv /usr/local/pgsql/data /usr/local/pgsql_90/data 

Then I recreated the symlinks in /pg_tbspc to point to the new directory path.

What does a listing for that directory look like after the move?

[pgsql@postgres-93-upgrade /tmp]$ ls -la /usr/local/pgsql_90/data/

What does a listing for the 9.3 directory look like?

 This is right after the initdb, I also created the /drupal_dbspace

So what do the listings for the old and new data directories look like after the upgrade?


Here is the moved 9.0 directory, it's a listing of data, drupal_dbspace, and pg_tblsp
