Hi Eli, sorry for taking to long to get an answer for you on this, I had
to find someone in Canonical who could tell me what the options are, and
then it appears I accidentally deleted this email thread.

The Snap store that Canonical runs has a features called "Update
control" designed for device makers, which lets them specify what
versions of other snaps can be installed on their device. This would let
you specify, in your own snap, which version of couchdb will be used on
your device. You can then update that information in your snap in the
store, and all of your devices will see that only then will they update
couchdb to the new version.

This is a commercial feature of the store, it's not available to regular
application snap developers. I'd be happy to put you in touch with
someone at Canonical who can tell you more about it and help you get
setup with it.
