RE : Postgres 8.0 + JDBC

OK Thanks a lot for your answer.
But as I'm a newbie in this field, could you give me an example of how
to do that.

I've already checked the array typename and it is "_text".

You said :
"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."

How to do that?

Thanks

JR

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.
