Hmm, that uninitialized value for p_perminfo is pretty suspicious.
I see that transformFromClauseItem and buildNSItemFromLists both
create ParseNamespaceItems without bothering to fill p_perminfo,
while buildNSItemFromTupleDesc fills it per the caller and
addRangeTableEntryForJoin always sets it to NULL. I think we
ought to make the first two set it to NULL as well, because
uninitialized fields are invariably a bad idea (even though the
lack of valgrind complaints says that the core code is managing
to avoid touching those fields).
If we do that, is it sufficient to resolve your problem?
