Try \d+ test_table. Hope that helps, Mike Mascari [EMAIL PROTECTED] -Original Message- From: Norman J.

You have to put the actual name (attribute) of the column, not "col1" On Fri, 16 Feb 2001 14:24, Norman J.

RE: [GENERAL] how to see column comments?
Actually, I responded a bit too hastily. That looks like a bug in psql to me. I see it in 7.0.3 as well. The query that psql is generating is incorrect: SELECT relhasindex, relkind, relchecks, reltriggers, relhasrules FROM pg_class WHERE relname='table.column'; It should be querying pg_attribute. It seems \d+ tablename is currently the only way to view column comments. Hope that helps, Mike Mascari [EMAIL PROTECTED] -Original Message- From: Norman J.
