Point taken.

PL/SQL requires all DDL to be dynamic SQL.  For example:
execute immediate 'drop table foo';

The stuff inside the string is pretty-much ignored at compile time.

Maybe, then, my idealized PL/pgSQL compiler always allows DDL to
reference any object, but DML is checked against the catalog.
