Ответ на drop column?  (Jodi Kanter <jkanter@virginia.edu>)
Список pgsql-admin
Jodi,

Of course, we should have 'alter table .... drop column ....' statement.
>Can I remove this column or will I need to drop the entire table and
restore from backup?
You can do as following:
select fields_you_want_to_keep into new_table from old_table.
Make sure that this statement execute successfully. Then drop the old table
and change table name (alter table ... rename to ...).
I am a newbie of postgres.

I cannot seem to locate any documentation about removing a column that I
just added to a table. There is no data in that particular column but there
is in the rest of the table.
Can I remove this column or will I need to drop the entire table and restore
from backup?
Thanks
Jodi
