If I good understand you, you don't reject strftime idea. I try it..

:-)) yes '||' is good. I said it bad. I think exapmle inetcat() (I
programming this for my project):
select inetcat('160.217.1.0/24', 50);
inetcat
------------
160.217.1.50
In my prev. letter I said it generally. (I'am finding a more function
in PSQL.. and I can try write it.).
