Would it be appropriate for ValueGeneratedOnAddOrUpdate() to throw a NotImplementedException? I spent a fair amount of time today to discover that this adds nothing.
Using v 2.2.4
from efcore.pg.
@TPucke @austindrenski EF Core 3.0.0 actually added support for the upcoming PostgreSQL 12 generated columns, so this will start working (see these docs). We previously had a clear doc note saying that this feature wasn't available on PostgreSQL.

Same for defining a property as ValueGeneratedOnAdd
from efcore.pg.
@101ship-it I don't think ValueGeneratedOnAdd
is the same as ValueGeneratedOnAddOrUpdate
, the former is natively/easily supported in PostgreSQL, e.g. by defining a default value for a column... Or am I missing something?
from efcore.pg.

agreed - they can be done differently - i was just meaning that ValueGeneratedOnAdd also doesn't work yet.
from efcore.pg.
Note that this is not the same as #19, which is about xmin as a special case (for concurrency token).
from efcore.pg.
This is probably out of scope of an EF Core provider.
Users can still use raw SQL in migrations to set up triggers which can implement ValueGeneratedOnAddOrUpdate.
from efcore.pg.
@TPucke At this point, probably not... That would very likely break code in the wild, which wouldn't be great from a patch release.
Emitting a warning sounds more plausible, but I'd need to take another look at the 2.2 architecture. Could you open a new issue with some sample user code showing when/where you expect the warning/exception to happen?
