FWIW, we took a slightly narrower approach to this issue in the 
pgBackRest patch (attached).

I don't have an issue with the prefix approach since it works and the 
Postgres project is very likely to catch it if there is a change in 
behavior.

For third-party projects, though, it might pay to be more conservative 
in case the behavior changes in the future, i.e. 
pg_internal.init[something] (but not pg_internal\.init[0-9]+) becomes valid.
