No, they do to the PostgreSQL client, which is in C.

SQL cannot be interfaced at all, unless embedded.

I don't understand this. Of course they can and they did. The Ada interface
used exactly this way of parameter passing. Where is a problem.

All problems are on the client size, which is untyped because C cannot
capture the set of DB types, and RDBMS is unable to describe the semantics
and internal representation of these types. Ada cannot save you of you are
sitting on top of a cesspit. You are already there, enjoy it!
