Right! The rewrite code assumes that the resdomno of the
updated columns match the attribute number in the target
relation. I don't know if the join is messing it up - but
looks like. Thanks for the help - I think I have to look for
usage of p_last_resno to find all the places where this can
happen.
Little joke:
At the place in analyze.c, where a TLE is created, there is a
comment that not creating a proper target list with correct
resdomno's might break rules :-)
I love those comments. And especially all that have XXXXX
somewhere.
