RE: 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,

Subject: [GENERAL] how to see column comments?

Hello,

I have not been able to get psql to show column comments in version
7.1beta4. Am I doing anything wrong, or is this a bug? A transcript of my
psql session is below.

norman=# create table test_table (col1 integer);

CREATE

norman=# comment on table test_table is 'this is a table comment';

COMMENT

norman=# \dd test_table

Object descriptions
Name | Object | Description

test_table | relation(r) | this is a table comment
(1 row)

norman=# comment on column test_table.col1 is 'this is a column comment';

COMMENT

norman=# \dd test_table.col1
