Just do elog(NOTICE) inside the loop over indexes, rather than setting a
flag to do it later. For that matter, I see no reason not to raise the
elog(ERROR) condition inside the loop, rather than setting a flag to
do it later.

To make a zero-based C array index from the one-based attribute number.
But the problem with this code is it doesn't handle indexes on system
attributes such as OID, which have negative attribute numbers and are
not shown in rel->rd_att->attrs. I'd be inclined to use get_attname,
and not bother with looking into the relcache rd_att structure at all.

get_rel_name
