Hmm. I confess to not having paid enough attention to this, but:
1. Loggedness is not a word. I think that "persistence" or
"relpersistence" would be better.
2. The patch seems to think that it can sometimes be safe to change
the relpersistence of an existing relation. Unless you can be sure
that no buffers can possibly be present in shared_buffers and nobody
will use an existing relcache entry to read a new one in, it's not,
because the buffers won't have the right BM_PERSISTENT marking. I'm
very nervous about the fact that this patch seems not to have touched
bufmgr.c, but maybe I'm missing something.
