Compound foreign keys are not joined correctly about honeyeql HOT 4 OPEN

Thanks @sparkofreason, for reporting this issue.

I can reproduce it with the below schema

CREATE TABLE account (
   acc_num INTEGER,
   acc_type INTEGER,
   acc_descr CHAR(20),
   PRIMARY KEY (acc_num, acc_type));

CREATE TABLE sub_account (
   sub_acc INTEGER PRIMARY KEY,
   ref_num INTEGER NOT NULL,
   ref_type INTEGER NOT NULL,
   sub_descr CHAR(20),
   FOREIGN KEY (ref_num, ref_type) REFERENCES account);

Currently, it generates four relationship attributes

:account/ref-num-sub-accounts
:account/ref-type-sub-accounts

:sub-account/account-by-ref-num
:sub-account/account-by-ref-type

Post this fix (which I will address in a week's time), It will have two extra relationship attributes

:account/sub-accounts

:sub-account/account

Which will join based on the composite foreign key.

@sparkofreason I did some initial analysis today. It is a bit more complicated than I initially thought. If I am not wrong, it will take at least half a day of work. So, it won't be possible for me to work on it this week. Let me try my best to find some time to wrap this up!

Hi @sparkofreason,

It took way more than I expected, and thankfully, I used the holidays effectively to bring it to closure.
