Hi,

One fairly simple way would use a new SQL verb (say, DO) like this:
DO $$ something in plfoo$ $ LANGUAGE plfoo;
We could even default the langauge to plpgsql, for which you would
then just need:
DO $$ something in plpgsql $$;
That would also be a nice feature to rely on in extensions install.sql
files when you have major version dependant code. Defining a function,
calling it then removing it is what to do now. This new syntax would
greatly simplify the support code.
DO $$
IF postgresql_major_version = '8.2'
THEN
...
ELSE
...
END IF;
$$;
(of course in this snippet example the ELSE covers it because the
CREATE EXTENSION stuff declared e.g. dependancy on postgresql >= 8.2).
