I think it's unjustifiable to show this in \d output. But maybe in \d+ output it could be justified, or perhaps in the \d++ which I seem to recall Alvaro proposing someplace recently. I think if we're going to show it, it should be on its own line, with a clear label, not just in the table header as you proposed. Otherwise, people won't know what it is. I suppose the work we'd need to make it work with the regression tests is no worse than the hide_tableam crock which Andres recently added. That is certainly a crock, but I can testify that it's a very useful crock for zheap development. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
