[ shrug... ] Depends what you consider "future proof". I should think
that if pg_type.typsend goes away or changes meaning, for example,
that would be reflective of changes large enough to break an extension
dabbling in binary I/O in other ways anyway.
Inserting new rows into pg_depend manually is a bit riskier, but I
don't think that catalog has changed since its inception, so it's
not all that risky.
In any case, you could limit the lifespan of the upgrade script,
if you roll it up into a new base install script ASAP.
