Обсуждение: About the char16 and char(16);

hi,
Can somebody tell me the difference in char16, char(16)?
I found a .c program in the package of the v6.3 of postgres that can
concat two char16 strings to one, is there any method that can easily
concat two char(80) or char(30) to a string?

try using concatenation operator ||

SELECT string_of_80 || string_of_30 FROM mytable;
it works.
