Обсуждение: Where does postgres store records of DROP-ed columns?

Hello,

I  have some stuff coming back from the database
telling me that columns that I have dropped
are being retined inthe table renamed as

........pg.dropped.1........
........pg.dropped.7........

I know what these columns originally were but I dropped them
from the table. I am now 'haunted' by these ghost columns with no
type applied.

How do I get rid of these references?

Thanks for nay help,

Pete

I believe (I would have to double check) that they will dissappear after
a vacuum.

Sincerely,

You ignore pg_attribute rows that have attisdropped true.

            regards, tom lane

Thank you.
That worked.
I got mind locked into psql command line space and forgot about
the executables......

Thanks again,

Pete
