Well, at this point the right thing to do is contact the developer of
the informix FDW. The bug is most likely in that code rather than
the core server, and even if it isn't, we'd need their cooperation to
narrow it down. This list is primarily for handling bugs in the core
server, so it's likely the FDW's author doesn't read it (or at least
hasn't noticed this thread).
