no. arbitrary SQL is no problem,
arbitrary plpgsql must be declared as a function so that it can be
compiled and run. (compiling is automatic)
inside a function execute can be used but not all plpgsql can be
executed (but, again, you can use execute to define and run a new function)

You seem to be wanting something like "anonymous functions". postgres
doesn't do them yet. It may in the future, or they may be incompatible
with the design.
