commenting on polymorphic aggregates possible?
-- value-independent transition function
CREATE AGGREGATE newcnt (
sfunc = int4inc, basetype = 'any', stype = int4,
initcond = '0'
);
COMMENT ON AGGREGATE newcnt (any) IS 'an any agg comment';
ERROR: syntax error at or near "any" at character 30
COMMENT ON AGGREGATE newcnt (any) IS NULL;
ERROR: syntax error at or near "any" at character 30
Is there any way of commenting that aggregate?

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 :-(
