Hello,

Here are the latest patches for my temporal tables work. They are 
rebased on e8d74ad6 from Aug 31.

I incorporated Peter's edits mentioned above and have made various other 
improvements.

The most significant change is support for partitioned tables. Those now 
work with temporal PRIMARY KEY and UNIQUE constraints, FOR PORTION OF 
commands, and FOREIGN KEYs.

I've tried to clean up the first four patches to get them ready for 
committing, since they could get committed before the PERIOD patch. I 
think there is a little more cleanup needed but they should be ready for 
a review.

The PERIOD patch is not finished and includes some deliberately-failing 
tests. I did make some progress here finishing ALTER TABLE ADD PERIOD.

I could use help handling the INTERNAL depenency from the PERIOD to its 
(hidden) GENERATED column. The problem is in findDependentObjects: if 
you drop the PERIOD, then Postgres automatically tries to drop the 
column (correctly), but then it seems to think it needs to drop the 
whole table. I think this is because a column's object address is the 
table's object address plus a subaddress equaling the attno, and 
findDependentObjects thinks it should drop the whole thing. I'm sure I 
can sort this out, but if anyone has a suggestion it might save me some 
time.

Thanks for taking a look!

Yours,
