Hi Hackers,
Here is another set of commits. Based on discussion on the thread
about Index AM API Cleanup [1], I decided that I should just always
make FOR PORTION OF infer its intersect proc from whatever intersect
op is used by temporal foreign keys (even though we don't have a way
to get an intersect op for non-range/multirange types yet). This means
we need one less GiST support proc, which seems like a nice improvement.
I also fixed the RESTRICT commit where a change previously was
included in a later commit that should have been included there.
Rebased to 29dfffae0a, fixing a merge conflict + crash with the NOT
ENFORCED commit.
I have committed the fix for foreign key NO ACTION (patch 0002, this did
not require patch 0001). I will study the proposed fix for RESTRICT
(patches 0001 and 0003) next.
I think my interpretation of what RESTRICT should do is different.
The clause "Execution of referential actions" in the SQL standard only
talks about referenced and referencing columns, not periods. So this
would mean you can change the period columns all you want (as long as
they maintain referential integrity). So it would be like the NO ACTION
case. But you can't change any of the non-period columns on the primary
key if they are referenced by any referencing columns, even if the
respective periods are disjoint.
Maybe this makes sense, or maybe this is a mistake (neglected to update
this part when periods were introduced?). But in any case, I can't get
from this to what the patch does. When I apply the tests in the patch
without the code changes, what I would intuitively like are more errors
than the starting state, but your patch results in fewer errors.
If we're not sure, we can also disable RESTRICT for now. We have to get
NO ACTION right first anyway, given the other messages in this thread.
