I looked some more at important areas where changes didn't have code
coverage. One thing I noticed was that the "non-internal" part of
AbortCurrentTransaction() is uncovered:
https://anarazel.de/postgres/cov/16-vs-HEAD-2024-04-14/src/backend/access/transam/xact.c.gcov.html#L3403
Which made me try to understand fefd9a3fed2. I'm a bit confused about why
some parts are handled in CommitCurrentTransaction()/AbortCurrentTransaction()
and others are in the *Internal functions.
I understand that fefd9a3fed2 needed to remove the recursion in
CommitTransactionCommand()/AbortCurrentTransaction(). But I don't understand
why that means having some code in in the non-internal and some in the
internal functions? Wouldn't it be easier to just have all the state handling
code in the Internal() function and just break after the
CleanupSubTransaction() calls?
That's of course largely unrelated to the coverage aspects. I just got
curious.
