Too short field

Hi,

We solved the problem of yesterday where I was looking at sequences. It eventually turned that sequence was irrelevant (at least in the PostgreSQL sense) to the problem.
Now, we have a bug in another application that prevents an automatic tool to enter certain users in the database. The organisational field is varchar(60) while the actual Organisation "abbreviation" may be as long as 70 characters (don't ask why).
What happens to data if I simple redefine the table field as varchar(80) (or something, at least 70+). Does "everything" break database side or can I just go on running the app as is.
Do we need to restart databases or something else that requires an interrupted service?

Best regards,
Martin S
