It is not criticism but only my own thought and PG is a really great database!!! It was all perhaps due to my poor understanding of relhasindex from pg_class internal catalog and I understand and respect your view.

Note that UNIQUE constraints are implemented by indexes too, so it's not clear to me that special-casing the pkey would really respond to this criticism anyway. But the bottom line is that relhasindex is defined in terms of possessing physical indexes, not whether those indexes arose from constraint syntax or CREATE INDEX. regards, tom lane Attention: The information contained in this message and or attachments is intended only for the person or entity to which it is addressed and may contain confidential and/or privileged material.
