That's what I thought, so it won't do what I want. I need to be able to set the length at the time of declaration.
So suppose I wanted to implement myvarchar in C. In my _in function, how do I know how big my column declaration is? Eg
ifsomeone tries to insert 50 characters into my 42 character field, how do I get the declared length and then tell
postgresthat the data to be inserted is too big?
Thanks
