Re: changing the size of a column without losing data

Hi !

One quick way to do this is to take a dump from your x_db. Edit the dump file
and change your field's defition from character varying(100) to character
varying (50)

Make sure the data is valid for this shorter field. Drop your x_db. Create a
new empty x_db. Read the dump in the new x_db.
