Test failures on Oracle -- ORA-01658: unable to [enlarge] tablespace

[Shai Berger]

Consistently, in the last few runs on CI on all Python versions, and also reproduced on my machine:

Notes:

1. This is on 1.7.x only -- on master, this has been solved for good by the fix to #21775.
2. This only shows up when running a lot of tests, although the failure is consistently in the same test.

[1.7.x] Fixed #23969: Made Oracle default test-tablespace larger.

It seems our test suite has grown...
Refs #21775

[Tim Graham]

Shall we add a mention to the 1.7.2 release notes about this since it presumably also affects anyone who is running their own tests on Oracle?

Also the 1.8 release notes could be updated; it currently says "The default max size of the Oracle test tablespace has increased from 200M to 500M."

[Shai Berger]

Yes, I thought it wasn't needed but you're right. I'll take care of it later (hopefully today).
