I already have code for that. I'll submit next version once I'll go over
PeterE's review. BTW the relcache thing is not as bad as it seems from
the publication patch because output plugin has to deal with
relcache/publication cache invalidations, it handles most of the updates
correctly. But there was still problem in terms of the write filtering
so the publications still have to reset relcache too.
