Yes, indeed. My code has a lot of unnecessary and error-prone input
validation checks because I don't trust the PostgreSQL parser.

That's scary. You don't trust your database that it processes a
simple text string, yet you still believe that it keeps all the data
you store, although this involves much more complex data structures
and algorithms.

What a strange asymmetry!
