setArray has never worked particularly well; you're seeing another
manifestation here.
The underlying problem here is that:
- setArray() is claiming that the type it is setting is a VARCHAR
- the parameter is being passed as a typed parameter via the V3
protocol, with type = 'text'
- apparently you can't cast directly from text -> text[] (although you
can interpret an untyped literal as text[], which is why it worked before).
It seems possible to fix the driver to handle this case by making
setArray() derive a proper array type name i.e. ("_" +
Array.getBaseType()), and using that rather than 'text' as the parameter
type.
I'll try to do this soon, but I'm a bit busy so it may be a few days.
A longer term fix is to properly implement array support in setArray()..
I've submitted patches in the past to do this but they've never made it
into the official driver.
