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)
