Обсуждение: How to force some char type columns to be stored in uppercase

in 8.1+ many char(n) type columns must be in uppercase in database.
What is best way to force this ?

Should insert and update triggers created for every table or is there better
way,
for example by creation domain or adding some attribute to column and
creating global trigger?

A simple trigger like this should work fine. You're basically throwing
an upper() around the field in a function and calling that a trigger.
If you decided to do it in the application, then throwing a constraint
around each updated / inserted text col is pretty easy too.
