+Results after syncing the dabatase
+----------------------------------
+
+After syncing the database, you'll see in the console the following:
+
+```
+Executing: CREATE TABLE IF NOT EXISTS "Trainer" ("first_name" VARCHAR(255), "last_name" VARCHAR(255), "id"   SERIAL , PRIMARY KEY ("id"));
+Executing: CREATE TABLE IF NOT EXISTS "Series" ("title" VARCHAR(255), "sub_title" VARCHAR(255), "description" TEXT, "trainer_id" INTEGER REFERENCES "Trainer" ("id"), "id"   SERIAL , PRIMARY KEY ("id"));
+Executing: CREATE TABLE IF NOT EXISTS "Video" ("title" VARCHAR(255), "sequence" INTEGER, "description" TEXT, "series_id" INTEGER REFERENCES "Series" ("id"), "id"   SERIAL , PRIMARY KEY ("id"));
+```
+
+Notice in the `Video` that `series_id` field has a referential integrity to `Series`:
+
+```
+"series_id" INTEGER REFERENCES "Series" ("id")
+```
+
+This is the output when describing the table's structure of the Postgres database:
