That did the trick.  However, I now have another problem with the constraint 
complaining about there not being an index to refer to.  However, there is.  
Output below:

create table ranks (
rid     	int4 default nextval('ranks_rid_seq'::text) unique not null,
rdid		character references depts(did), -- department
rrank		int4 not null,		-- departmental rank
rdesc		character varying(40)	-- Rank Description
);
NOTICE:  CREATE TABLE/UNIQUE will create implicit index 'ranks_rid_key' for 
table 'ranks'
NOTICE:  CREATE TABLE will create implicit trigger(s) for FOREIGN KEY check(s)
CREATE
create unique index "ranks_drank_index" on ranks using btree ("rdid", 
"rrank");
CREATE
create table jobtypes (
jid     	int4 default nextval('jobs_jid_seq'::text) unique not null,
jdid		character,		-- This joint reference
jrank		int4 not null references ranks(rrank),	-- needs sorting
jdesc		character varying(40),	-- job description
constraint c2 foreign key (jdid,jrank) references ranks (rdid,rrank)
);
NOTICE:  CREATE TABLE/UNIQUE will create implicit index 'jobtypes_jid_key' for 
table 'jobtypes'
NOTICE:  CREATE TABLE will create implicit trigger(s) for FOREIGN KEY check(s)
ERROR:  UNIQUE constraint matching given keys for referenced table "ranks" not 
found
