Correct.

That's basically what you've got to do. There've been discussions on
and off about providing a direct command to execute an anonymous,
transient PL function definition, along the lines of
PERFORM 'begin
... blah blah ...
end'
LANGUAGE plpgsql;
but no one's really put forward a complete plan to deal with this
(what about arguments and a return value?).
Note that there is approximately 0 interest in promoting any one
PL to the exclusion of others, so a command syntax that presumes
which PL is to be executed isn't going to happen any time soon.
