Even if we did, I don't think it'd affect this decision.
The real problem in my mind is one of user expectations. If the database
silently does something behind your back, people expect that that action
will be *right* and they don't have to worry about it. I don't think
that automatically reparsing views has much chance of clearing that bar.
In much simpler, non-extensible SQL systems it could probably work, but
for better or worse Postgres has gone all-in on datatype extensibility.
