What is probably surprising the OP is that applying the || operator involves a coercion from "char" to "text", which strips the defined-to-be-insignificant trailing space(s) of the "char" value. As David said, you're best off not using the char type. The semantics around trailing spaces are too squishy for my taste, and there's no real advantage compared to varchar or text. regards, tom lane
