One thing from the commit-message:

"On-disk, we can still store it in words, so as to not break on-disk
compatibility with beta1."

Hasn't that ship already sailed?

from beta1 to HEAD:

The database cluster was initialized with CATALOG_VERSION_NO
201605051, but the server was compiled with CATALOG_VERSION_NO

Or is the concern about intra-version pg_upgrade rather than direct
on-disk compatibility?
