Hmm, no.  I still get the NOTICE. How can I create the primary key
without triggering a NOTICE?


bnesbitt=> create unique index test_5_pkey on test_5 (userid, site_key);
CREATE INDEX

bnesbitt=> alter table test_5 add primary key (userid, site_key);
NOTICE:  ALTER TABLE / ADD PRIMARY KEY will create implicit index
"test_5_pkey1" for table "test_5"
ALTER TABLE

bnesbitt=> \d test_5
           Table "public.test_5"
+-------------------+---------+-----------+
|      Column       |  Type   | Modifiers |
+-------------------+---------+-----------+
| userid            | integer | not null  |
| site_key          | integer | not null  |
| ranking_365       | integer | default 0 |
| downloads_total   | integer | default 0 |
| ranking_total     | integer | default 0 |
+-------------------+---------+-----------+
Indexes:
    "test_5_pkey1" PRIMARY KEY, btree (userid, site_key)
    "test_5_pkey" UNIQUE, btree (userid, site_key)
Foreign-key constraints:
    "test_5_site_key_fkey" FOREIGN KEY (site_key) REFERENCES
contexts(context_key) ON DELETE CASCADE
    "test_5_userid_fkey" FOREIGN KEY (userid) REFERENCES users(userid)
ON DELETE CASCADE
