If you think relpathbackend() alone warrants that, yes, I can provide a
wrapper. Everything else is imo already handled in a sensible and not
really ugly manner? Imo its not worth the effort *for this alone*.

I already had some elog(), ereport(), whatever emulation but Heikki
preferred not to have it, so its removed by now.

To what extent do you want palloc et al. emulation? Provide actual pools
or just make redirect to malloc and provide the required symbols (at the
very least CurrentMemoryContext)?
