I would vote +1 for back-patching a fix for this problem (that is,
pushing it into the minor releases), because I agree that it's very
arguably a bug that we treat the segments differently, and looking
around I do see reports of people having to terminate processes to get
their disk space back. I'd definitely want a consensus on that plan
from some experienced reviewers and testers, though. For anyone
wanting to test this, you might want to set RELSEGSIZE to a smaller
number in src/include/pg_config.h.
