Yes. You should enable all of the following settings:

debug_print_parse (boolean)
debug_print_rewritten (boolean)
debug_print_plan (boolean)
debug_pretty_print (boolean)

which you can do dynamically from psql.

Then post the output for both the failing version (on that table where
you can reproduce the issue), and the other table where it seems that
you ought to be able to reproduce the problem, but you can't. Maybe
that'll show where the problem is.

Thanks
