OK, so I've created a draft patch which does this.

In summary of what it does

1. Renames all wal_location functions to wal_lsn.
2. Renames all system view columns to use "lsn" instead of "location"
3. Rename function parameters to use "lsn" instead of "location".
4. Rename function parameters "wal_position" to "lsn". (Not mentioned
before, but seems consistency was high on the list from earlier
comments on the thread)
5. Change documentation to reflect the above changes.
6. Fix bug where docs claimed return type of
pg_logical_slot_peek_changes.location was text, when it was pg_lsn
(maybe apply separately?)
7. Change some places in the func.sgml where it was referring to the
lsn as a "position" rather than "location". (We want consistency here)

Is this touching all places which were mentioned by everyone?
