postgresql arrays? about drift

[simolus3]

No problem - the fact that the custom type has to be specified twice here not intuitive at all, I consider this to be a flaw in drift. It's just not easy to fix...

I think the postgres package only supports some array types, but we should definitely have support for those in drift_postgres.

Or is there a dark magic way with custom queries?

You can use custom SQL types as a workaround until we have official support for them. That's not even dark magic, an official API in package:drift_postgres will be built with the same thing :)

I've added them to drift_postgres in c621ef9.

Sweet, thanks :D

Oopsies, totally forgot about this functionality, my bad

Hmm, it seems I can get it working with default values

class User extends Table {
	Column<List<int>> get example => customType(PgTypes.bigIntArray).withDefault(const Constant([]))();
}

Throws :

Invalid argument (dart): Must be null, bool, String, int, DateTime, Uint8List or double: _ImmutableList len:0

[simolus3]

Ah right, I think you'd have that problem with all custom types - at the moment we're unfortunately unable to infer the type to apply in that context.

Does it work if you explicitly apply the type on the constant, e.g Constant([], PgTypes.bigIntArray)?

[Noxits]

It indeed does, thank you very much.

Sorry, I should really open my eyes somehow, the solution was right in front of me..
