Hello everyone,
I have created a new data type "mychar". How can I specify a limit for it?

This (unlimited version) works fine:
create table table_a(col_a mychar);

What you want is called "user defined typmod" and I don't beleive any
released version has it, but it will be in the next release.

I believe he could do it with a domain.

create domain myreal_char as varchar(50);
create table table_a(col_a myreal_char);
