After release we got reports about big consumption of UNDO_TBS, TEMP_TBS and slowness of the upgrade from sat520 to sat530
This bugzilla will track each individual problem.
To restate all upgrade problems discovered after 5.3.0 release:
* schema upgrade may consume significant amount of undo tablespace (and
run out of available space)
* schema upgrade may consume significant amount of temporary tablespace
at several places (and run out of available space)
* update-packages script may consume significant amount of undo tablespace
and run out of available space resulting into database data being inconsistent
with filesystem data
* update-packages script does not handle epoch information during /var/satellite
upgrade correctly
