Hmmm .... this code has got a number of problems, but I don't see why
*that* would fail. Anyone?
What I do see:
1. Should not "break" out of loop over indexes after detecting a
matching non-primary-key index. This allows detection of the NOTICE
condition to distract you from detecting the ERROR condition on a
later index. I'd suggest issuing the NOTICE inside the loop, actually,
and not breaking at all. (See also #4)
2. What's with the "if (keyno > 0)"? That breaks detection of
everything on indexes on system columns, eg OID. (Of course, the
"rel_attrs[keyno - 1]" reference doesn't work for system columns,
but sticking your head in the sand is no answer.)
3. pfree'ing iname at the bottom doesn't strike me as a good
idea; isn't that possibly part of your input querytree?
4. If you're going to be so pedantic as to issue a warning notice about
a duplicate non-primary index, it'd be polite to give the name of that
index. Else how shall I know which index you think I should drop?
