Hi, there is a feature that I would be glad if it was supported by PostgreSQL: I want to add a new column (attribute) to a pre-existed table, but instead of filling the values of this column with a default value (e.g. null) I would like to copy them from a file stored in my filesystem. I didn't find any example of mixing "copy" and "alter table ... add column" in the Documentation, however I send this mail to check it out. Thanks.
