If it's difficult to come up with something that will work for all
table AMs, then it suggests that we might want to go towards fully
extensible rmgr, and have a decoding method in the rmgr.
I started a thread (with a patch) here:

Agreed, but it seems like we need basic extensibility first. For now,
we'll need to convert to a heap tuple, but later I'd like to support
other formats for the decoding plugin to work with.
