Select from Postgres into Struct array GO

So i have this struct

type MessagesStored struct {
    MessagetoStream string
    StreamSub       string
    PubName         string
    CreatedAt       time.Time
}

And i have a table in Postgres to match the struct

CREATE TABLE "StoredMessages"
(
    "Message" character varying(200) COLLATE pg_catalog."default" NOT NULL,
    "PubName" character varying(50) COLLATE pg_catalog."default" NOT NULL,
    "Subject" character varying COLLATE pg_catalog."default" NOT NULL,
    "CreatedAt" timestamp with time zone
)

So i am trying to select all the rows where a subject matches a string and store them in an array of the struct

var OldMessages []MessagesStored
db.Query("SELECT * FROM StoredMessages WHERE Subject = ", FilterSub)
    for rows.Next() {
        var oldmessages MessagesStored
        errrws := rows.Scan(&oldmessages.MessagetoStream, oldmessages.StreamSub, &oldmessages.PubName, &oldmessages.CreatedAt)
        CheckError(errrws)
        OldMessages = append(OldMessages, oldmessages)
    }
```
