While most of this patch set makes no behavior changes by design, I
should point out this little change hidden in the middle:

Remove deprecated syntax from CREATE/DROP LANGUAGE

Remove the option to specify the language name as a single-quoted
string. This has been obsolete since ee8ed85da3b. Removing it allows
better grammar refactoring.

The syntax of the CREATE FUNCTION LANGUAGE clause is not changed.

(ee8ed85da3b is in PG 7.2.)

I expect this to be uncontroversial, but it should be pointed out.
