Re: altering data type in a column

The simple answer: No. What has been suggested here numerous times (check
the archives) is the following procedure:

pg_dump the table you want to change to a text file.
edit the dump file and change the CREATE TABLE section to have an int type
instead of char.
DROP the original table
read in ( \i ) the modified dump table.

You need to make sure that there are NO non-integers in the field you are
changing!
