For testing the packed varlena stuff it would have been handy to be able to see the length of tuples on disk. I made do with pg_column_size(foo.*) but it's not exactly the same thing I don't think. And I could see for debugging HOT and vacuum it would be helpful to see the physical layout of the tuples in the page. Ie, the offsets of each tuple (which Simon's function didn't actually output last I saw, but would be nice if it were added). -- Gregory Stark EnterpriseDB http://www.enterprisedb.com ---------------------------(end of broadcast)--------------------------- TIP 4: Have you searched our list archives? http://archives.postgresql.org
