I was thinking the most natural thing would be to use something similar to
COPY's stdin quoting:
CREATE FUNCTION bob() RETURNS INTEGER AS stdin LANGUAGE 'plpgsql';
BEGIN...
END;
\.
Another possibility would be shell/Perl-style here documents, like this:
CREATE FUNCTION bob() RETURNS INTEGER AS <<EOF
BEGIN...
END;
EOF
LANGUAGE 'plpgsql';
The former seems preferable since it uses a syntax PostgreSQL already
supports in another context.
