Right now, we have problems such as those mentioned in #10467 (comment 4). If a part of Django wants to use a particular feature that depends on the database version, it needs to first have talked to the database. This breaks in some edge-cases.
Some alternative possibilities are
- understanding deferred-features, but that looks hard. For example, it's difficult to imagine how "return ID from insert" can work in that fashion without being really ugly code.
- requiring the settings file to include the version information so we don't have to make the wasteful
SELECT version();(or equivalent) call for every database connection. It's essentially unchanging information.
Anyway, that's a discussion for later (I'll start a thread on django-dev at some point). Opening the ticket to remind me to look at this.
