Here is a series of patches to do some refactoring in the grammar around
the commands COMMENT, DROP, SECURITY LABEL, and ALTER EXTENSION ...
ADD/DROP. In the grammar, these commands (with some exceptions)
basically just take a reference to an object and later look it up in C
code. Some of that was already generalized individually for each
command (drop_type_any_name, drop_type_name, etc.). This patch combines
it into common lists for all these commands.
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.
