Re: String concatenation operator which keeps trailing spaces in CHAR(n) columns

Hi!

Thank you very much.
It worked.
Which notation to use for this ?

Is it reasonable use "+" as such operator for strings or should some other
notation used ?

I tried:

CREATE OR REPLACE FUNCTION public.concatkeepspaces(left bpchar, right
bpchar)
RETURNS bpchar
LANGUAGE sql IMMUTABLE
AS $BODY$
SELECT concat($1,$2);
$BODY$;

CREATE OPERATOR public.+ (
    leftarg = bpchar,
    rightarg = bpchar,
    procedure = public.concatkeepspaces
);
