This puzzles me too! I found that bizarre myself. What is even more

tablespace vol4 as default were copied from template1 without
explicitly specified tablespace name...

I've found that very bizarre myself, that default_tablespace would be
changed for already existing databases without me altering it
explicitly...
Sigh

However, since I have modified template1 (and most likely, those
databases were copied from it in the past), it changed
default_parameter for them as well.
This seems unlikely to be the case - changing template1 should not be
affecting other existing databases.

Previous actions may have altered (accidentally) the default table space
for those databases but this doesn't show that the tables of old are now
on vol4 does it?. Would have taken some time to move 80 non-trivial
databases.
