I don't disagree with removing the LSN column, but at the same time we
need to provide *some* way for users to monitor this, so let's add a
function to extract the value they need for that. It seems simple
enough.
I cannot implement it myself now, though. I've reached the end of my
week and I'm not sure I'll be able to work on it during the weekend.
I agree with Kyotaro's opinion that the pg_walfile_name() function seems
too single-minded ...
