Personall I think a system table containing information about all tables
in the database would be best. The contrib stuff provides a lot of
useful information which would be perfect for a system view (dead
tuples, number of records, ...). I guess many people would consider that
to be useful. This would not fix the COUNT problem but it would provide
the most essential information people need: The number of records in the
table.
Maybe this is worth discussing.
Regards,
Hans
