The implementation I was imagining was to define another bit in the info
parameter for XLogInsert, say XLOG_NON_TRANSACTIONAL. This could be a
high-order bit that would not go to disk. Anytime it was *not* set,
XLogInsert would set a global boolean that would remember that the
current transaction wrote a transactional WAL record. This is the
right default since the vast majority of call sites are writing records
that we would want to have flushed at commit. There are just a couple
of places that would need to be changed to add this flag to their calls.

If you have a patch in mind I'm happy to test it on my setup and report
back.
