Hi all,
i have a little question on changing the length of a varchar field.
Is there another way than dump and reload if i want to change the length
of a varchar field ?
I have search the idocs and found some docs about the system-table pg_attribute,
where the length of a varchar-field is stored in atttypmod.
Is it possible to change the value of atttypmod and is it safe to change this
value?
Thanks in advance
