psql: SELECT * ... except one column

To get the list of columns in default order, without the bad column:

SELECT string_agg(quote_ident(attname), ', ' ORDER BY attnum)
FROM   pg_attribute
WHERE  attrelid = 'myschema.mytable'::regclass
AND    NOT attisdropped  -- no dropped (dead) columns
AND    attnum > 0        -- no system columns
AND    attname <> 'bad_column'  -- case sensitive!

Or just WHERE attrelid = 'mytable'::regclass if you trust the search path to resolve to the right schema.

quote_ident() adds double-quotes where necessary.

I asked the same question in 2007 on pgsql-general. It was Postgres 8.2 back then. Sweet memories ...
