I've added a note there to inform users that the format might change.
People from other DBMSes - pretty much any other DBMS - tend to be
astonished that the file format changes incompatibly between releases,
especially between alpha and final for the same major. Given all the
buzz we get around new features and the way people leap to try them,
it's IMO worth making sure they understand that they need to think a
bit more when using a prerelease.
Added a following FAQ entry about the catversion, for when people
upgrade to a version with an incompatible format.
Feel free to remove if you think they're inappropriate/misplaced, or
copy-edit as desired. Hope it's helpful.
