This probably breaks these migrations:
20130801.pastexactions.php 20130805.pastemailkeypop.php
...which use PhabricatorPaste. If they run, the object will try to connect to _paste, but the data won't be there yet, since the migrations which later move it from _pastebin will not have run yet.
You can likely bin/storage upgrade --namespace test123 --no-quickstart to see them fail.
I think we have to deal with these on a case-by-case basis, which is a big part of why renaming phabricator_repository will be hard. Fortunately, these seem pretty easy:
- 20130801.pastexactions.php: I think we can just remove this. The data is not critical and the migration is almost 2 years old. Anyone who hasn't updated in the last 2 years can live without "x created this paste on such-and-such date." transactions.
- 20130805.pastemailkeypop.php: This is messy.
- We can remove it, then replace it with a similar new migration at HEAD. But this can only work because no intermediate migrations affect the object and the migration isn't particularly intrinsic to the object's state.
- We can update it in-place, but there's no way to connect to get a conn_w to the phabricator_pastebin database at HEAD. Particularly, when the migration executes, it will connect to phabricator_paste, which won't exist yet, then immediately fail. This seems complicated/hard in the general case, although maybe it's not that bad. We'd basically need a way to get a $conn to an arbitrary database by name.

I'm not convinced that it's a good idea, but in D13224 I toyed with the idea of allowing the "application name" to be override for this purpose.
Yeah, I saw D13224 after looking at this -- I think the general approach is probably fine, but I think we should expose some kind of explicit API to make it clear that some spooky black magic is occurring.
My ad-hoc DAO approach works with ./bin/storage upgrade --namespace test --no-quickstart, but currently fails on storage adjustment:

Although it mostly works, I am abandoning this diff because keeping it up-to-date seems like more effort than I am willing to give. It's not clear to me at this stage when (if ever) T8476 is likely to be resolved.
