I can see why this works now. The ddl_command_end option stops the
TAG being evaluated:
test2=# CREATE EVENT TRIGGER cmd_trg_before_any_command ON
ddl_command_end WHEN TAG IN ('MEOW LIKE A CAT') EXECUTE PROCEDURE
cmd_trg_info_any();
CREATE EVENT TRIGGER
...unless I've coincidentally stumbled upon the new MEOW LIKE A CAT
command coming in 9.3. ;)
