v26 attached here. It's been rebased and reflects most of the feedback.
A few incomplete items are marked as TBD here [1] and [2] is another thing
that needs discussion.
Besides that, I've done some refactoring in 0004: 1) move more code to
setup_logical_decoding(), and 2) reduced the number of arguments of
process_concurrent_changes() by using a new structure. Both these changes are
a preparation for a background worker that will perform the logical decoding,
but seem to be useful as such. (I have a PoC of the worker but will post it
later, it doesn't seem to be the priority for now.)
I've also removed support for decoding TRUNCATE because I realized that this
command uses AccessExclusiveLock, so it cannot be executed on a table that
REPACK (CONCURRENTLY) is just processing.
Also I tried to fix TAB completion in psql.

These are still pending.
