OK, so let's focus only on the renaming mentioned in $subject. So far
as I can see on this thread, here are the opinions of people who
clearly gave one:
- Rename them, hard break is OK: Michael P, Bruce, Stephen (depends on
David's input),  Magnus
- Rename them, hard break not OK: Fujii-san (perhaps do nothing?)
- Do nothing: Simon (add a README), Tom, Peter E

As far as I can see, there is a consensus to not rename pg_xlog to
pg_journal and avoid using a third meaning, but instead use pg_wal. I
guess that now the other renaming would be pg_clog -> pg_xact. Other
opinions? Forgot you here?
