According to `org-html-postamble' docstring, the function has to accept
one argument.

Again, according to `org-html-postamble' docstring, you need to set that
variable to t in order to use `org-html-postamble-format'. Then, by
looking at `org-html-postamble-format' docstring, you can see that only
%t, %a, %e, %d, %c, %v, %T and %C are allowed as format characters.

HTH,
