My immediate thought is that any indexes on non-text fields, created with these versions, will be useless in ORM-based queries. If that's the case, this seems like a much bigger deal than the footnote would imply.
I'm puzzled. Why you assumed that all non-string based fields are affected? Release note explicitly specifies what kind of indexes are affected: Indexes *"on string based fields (CharField, EmailField, TextField, CICharField, CIEmailField, and CITextField) used with the __isnull lookup on PostgreSQL".* Do you it's worth mentioning again after *"You may need to recreate indexes.."?* For example *"You may need to recreate indexes on string based fields (CharField, EmailField, TextField, CICharField, CIEmailField, and CITextField) used with the __isnull lookup propagated to the PostgreSQL database with Django 4.2 - 4.2.5, as they contain unnecessary ::text casting that is avoided as of this release."* Best, Mariusz -- You received this message because you are subscribed to the Google Groups "Django developers (Contributions to Django itself)" group.
