I was talking about pg_clearxlogtail. It is less fragile than
pglesslog because it doesn't look below the level of the page
structure -- it doesn't care about WAL record types at all. It
never needed one line of source code change until 9.3. Peter
Eisentraut was recently asking me questions about it and pointed
out that "It fails to build with 9.3devel, because of the change to
uint64 for WAL addressing."
Peter, do you have a version that works with 9.3?
Given that we're past the start of the last CF, do we still want to
consider including it? If you tilt your head at just the right
angle, I guess it could look like a bug fix -- but it is a stretch.
