My inclination is to leave these messages alone. They're not really
inconsistent with anything. Where we seem to be ending up is that
"lsn" will be used in things like function and column names, but
documentation will continue to spell out phrases like "WAL location".
There is another open thread about converting said phrases to be
more consistent --- a lot of them currently say "transaction log
location", which is not a very good choice because it invites
confusion with pg_xact nee pg_clog. But I think that's mostly
just documentation changes, and in any case it's better done as
a separate patch.

Yeah, probably s/log position/WAL location/ would be better here.
But again that seems like material for a separate patch. The
current patch does do s/position/location/ in a few places, but
it's not trying to apply that policy everywhere.
