Ref #33872
In case my mailing list comment gets lost, I make this as unreviewed and
leave a copy here:
Hi there,
I am sorry that I missed this in the alpha. But to the best of my
knowledge, CITEXT and non-deterministic collations are not the same. They
don't support the same operations and their string comparison operations
are similar, yet not identical.
Furthermore, PostgreSQL doesn't discourage the use of CITEXT, but hints
towards a native alternative. That's maybe more than just a subtle
difference.
99% of all use-cases might be email, but even email LIKE-queries would be
affected (good for +-searches).
Unless we want to drop support for the CITEXT extension, collations might
not be a sufficient replacement.
I'd caution to revert the deprecation and keep support unless we make an
informed decision to drop CITEXT for a 3rd party integration.
Best
Joe!
Update: We noticed vast problems while trying to migrate to collations in
Django admin. Sadly, this isn't straightforward and requires a lot of,
which solidifies my belief that we should revert the deprecation
altogether. Especially since the PG feature has no plans for
discontinuation.
I really appreciate the effort that was put into the initial commit. But,
weighting the user pain vs the rather marginal maintenance effort of the
DB type, seems maybe not worth it.
