doing via shell is one way (long way if you use Windows),
is it possible by updateding postgresql master tables?

Hi,

Hello,
I have in every table columns like:
username character varying(20) NOT NULL
I want to extend the length of varchar in all tables.
next time you should probably consider using a domain type
(or stick to text)
Since I have a lot of tables and mirrored backups, I am wondering if
there is a way to alter automatically all tables where colname matches
'username'
Is there a way to do this?
It should be possible to generate a list of tables either via
query or using pg_dump -L with grep and create SQL based on this
(with a script, unix shell) and execute it against the database.
(Test this of course)
