Re: BUG #4238: pg_class.relhasindex not updated by vacuum

Isn't a PK a CONSTRAINT and not an INDEX???
Some say "one or more fields" and others "one or more attributes" that
uniquely identifies a record in a table and PG like many other databases
would create a default internal index on that CONSTRAINT that can't be
seen or dropped unless you will drop the Pkey.
In that case the two separate pg_class relhasindex and relhaspkey would
make sense indeed - just a thought nothing else and we'll take it as is.

Best regards,

Uh, well certainly -- a PK is an index.
