At first glance, the Subject: of this thread made me think that *was*
Joel's proposal. :-) But I think it's a great idea, and worth doing.
I think "pg_journal" (no "x") is sufficient. The journal is an idea that
people are familiar with from filesystems anyway.

pg_clog could become pg_commits or pg_xactstatus or pg_commit_status or
something. What else is there? I'd hope pg_logical can be left alone.

I don't think it's necessary. (Of course, people have wanted to rename
pg_resetxlog to make it sound more scary anyway, but that's a different
matter.)

I'll agree with Joel that it comes up far too often for comfort anyway.
I've known a number of people who were on the verge of deleting stuff
from pg_xlog, but just happened to check with me first.
