XLOG_PAGE_MAGIC, for one. PG_PAGE_LAYOUT_VERSION doesn't change very
often, but might also fall into the same category.

Tablespace directory paths depend on the value of PG_MAJORVERSION.

It would be nice to have all of these documented somewhere along with
the criteria for bumping each one. It's relatively easy for a new
committer (ahem) to not realize that there's a version number that
needs to be bumped someplace, and recent experience has shown that
even an experienced committer can goof. :-)
