ANY is a reserved word. To reference the pseudotype named "any",
you need quotes:
COMMENT ON AGGREGATE newcnt ("any") IS 'an any agg comment';
No doubt it would've been better to use a different name for the
pseudotype, but I think the behavior of CREATE AGGREGATE's
"basetype = 'any'" was chosen long before there was any thought of
making Postgres SQL-compliant :-(
