Great to hear this - it's been on my wishlist for a while! Can you
please file a QEP about this specific change, as I'd like to hear the
implementation you have planned and have some related ideas which may
help.

As much as possible, can we follow the postgres naming/usage for array
handling functions?

Also on this note - at this stage of QGIS development I'd expect
(actually, scratch that - it's a *requirement*!!) that adding a new
supported field type would be absolutely soaked in unit tests,
including thorough testing for each provider which handling of these
data types are added to. Make sure you factor that into your proposal

Nice - this is annoying. Ping me if you have questions, as again I've
got a few ideas on how this can be fixed.
