More strict vendor checking (postgres) on the conditional index drop fix, on PR 149
This is the last planned pre-release for the `1.2.3` release.
1.2.3a4
Based on findings related to issue 142 from 136 we are at least temporarily rolling back to the previous behavior.
1.2.3a3
144 for issues on postgres (at least) for index creation/deletion management during the migration from an earlier PR from the user DB split (it was trying to fix something, and made a mistake trying to fix it).
This is a good fix for tests and anyone that hasn't yet upgraded to a release where the affected migration is present.
