I'm not sure what the issue was, I just made the CONSTRAINT look exactly like the PARTITION definition and then it worked. Thus I looked at the partition definition and it had a NOT NULL constraint as well as "without time zone".
I had done this before and it had worked. 12 hours, then swapping it in and it hung again, i.e. I was like "what, is the google procedure changing the wrong data?" I want as far as validating the whole table, i.e. I would add the constraint NOT VALID, run the google procedure to make it valid in the data dictionary, then attach it as a partition and and and. If there is no constraint, then the database will scan the whole table to make sure it conforms to the partition time range. The science of the constraint is that when the constraint matches the partition constraint and is valid, the database will swap in the table immediately. I put a time range constraint on payments_old that matched the time constraints of the partition it was going to become. H "Authorization: Bearer $(gcloud auth print-access-token)" \
