Thanks for looking.  There was a bunch that I didn't do and tried to
convey that in the commit message.

The diff you sent seems to contain a mix of my ones and your
additional ones. If you can sort that out so it's just yours and
subtract the following, which I've already decided not to do.

* MergeConstraintsIntoExisting -- I don't want to touch these for ALTER TABLE.
* record_recv -- Not done. First loop could be done but 2nd loop needs
atttypid, so Form_pg_attribute needs accessed regardless
* record_send -- Not done. First loop could be done but 2nd loop needs
atttypid, so Form_pg_attribute needs accessed regardless
* ATExecAddColumn -- I don't want to touch these for ALTER TABLE.
* CatalogTupleCheckConstraints -- Not done. This is just for Asserts
* ATRewriteTable -- I don't want to touch these for ALTER TABLE.
* ATAddForeignKeyConstraint -- I don't want to touch these for ALTER TABLE.
* set_attnotnull -- I don't want to touch these for ALTER TABLE.
* FreeTupleDesc -- Not done. I'd rather not use CompactAttribute here
just in case someone forgets to flush changes before freeing the
TupleDesc
* get_sql_insert -- Not done.  There are two loops, only 1 can use
CompactAttribute.

Thanks
