Hi,
Hugo Mercier (in Cc) reported me an error in a query, failing since pg10.
Simple test case to reproduce:
CREATE TABLE public.test (id integer);
WITH test AS (select 42) INSERT INTO public.test SELECT * FROM test;
which will fail with "relation "test" cannot be the target of a
modifying statement".
IIUC, that's an oversight in 18ce3a4ab22, where setTargetTable()
doesn't exclude qualified relation when searching for special
relation.
PFA a simple patch to fix this issue, with updated regression test.
Regards.
