Impossible to specify different port number in open-database with CCL1.10

Using CCL on a Mac (Version 1.10-r16196 (DarwinX8664)),

when I try to open a connection specifying a port:

(cl-postgres:open-database “database” "user” "pwd" "localhost" :port 5434)

the following error is raised:

value :PORT is not an integer from 1 to 65535 ((INTEGER 1 65535))

But even if I try to coerce it explicitly, with something like:

(cl-postgres:open-database "database" "user" "pwd" "localhost" :port (coerce 5434 '(integer 1 65535)))

the same error is raised.

Maybe this depends on CCL, since when I write to the REPL: (type-of (coerce 5434 '(integer 1 65535))) the answer is: (INTEGER 0 1152921504606846975)

So, may I suggest to change the parameter check to perform an explicit test on the limits?

Thank you very much for your attention
