@morozov am I on the right track with this? It seems a bit complicated.

As I understand, you want to create wrapper classes that will expose some unified interface for DBAL 4 and 5. That looks about right.

As a second thought, is it really necessary for ORM to support DBAL 4.2.x and 5.x? If it bumps DBAL requirement to 4.3.x, then it can switch to the new API without the need to implement the wrapers.

The issue isn't that 4.2.x needs to be supported (otherwise indeed I would bump), the issue is that 3.x needs to be supported 😢

I think there's something fundamentally wrong with this requirement.
DBAL deprecates its old APIs and provides a forward compatibility layer exactly in order to help its consumers migrate from one major release to the other (two in total) w/o building any compatibility layers themselves. ORM, on the other hand, aims at supporting 3 major DBAL releases (3 through 5) and thus has to maintain its own compatibility layer.
Maybe instead of building a compatibility layer, this effort could be spent on dropping support for DBAL 3?

Should I maybe be using toString here? I fear that the platform won't be always available in places where I should use these methods, for instance here:
orm/src/Mapping/Driver/DatabaseDriver.php

If you want to represent names as strings for compatibility with DBAL 4, then toString() is fine. The contract is: toSQL(AbstractPlatform) will render the name so that it can be parsed by the platform in question; toString() will render the name so that it can be parsed by the corresponding name parser (i.e. converted back to object).
