Updated patchset contains more transparent definition of composite type for constant node and regression test for described above buggy case.
Is there any interest on the problem in this thread?
Probably everybody are too busy with upcoming release and other patches. Since this patch is a bug fix, it definitely should be considered. Please, register this patch at upcoming commitfest to ensure it wouldn't be forgotten.
Regression test changes (both .sql and .out) are essential parts of the patch. I see no point in posting them separately. Please, incorporate them into your patch.
Did you check this patch with manually created composite type (made by CREATE TYPE typname AS ...)?
