在GoLang中运行SQL查询时，PQ Relation不存在

When running any sql query to my database in GoLang, i get the below error, does anyone know if there's anything else I can try to resolve the issue

pq: relation "users" does not exist

What I have tried:

Checked the permissions on the DB and all is okay.
Checked the credentials are okay
Ran the INSERT statement directly on the SQL database via psql
Created a minimalist program to make sure it wasn't anything else in my code
Entered values into query string manually, rather than using parameters
Tried SELECT statement and same issue. It just isn't finding the users table.
I have built the connection string through const variables, and as I have below. Neither have worked.
I have tried with, and without the port (5432)

The code below is what I have (the minimalist application outputting the same error as my main application)

func main() {
sqlInfo := fmt.Sprintf("postgres://postgres:postgres@localhost/user_details?sslmode=disable")

db, err := sql.Open("postgres", sqlInfo)
defer db.Close()

if err != nil {
    fmt.Fprintf(os.Stdout, "Connection to the database failed")
    return
}
err = db.Ping()

if err != nil {
    fmt.Fprintf(os.Stdout, "Connection to the database failed")
    return
}

fmt.Fprintf(os.Stdout, "You have connected to the database successfully")

sqlQuery := `INSERT INTO users ("user_id", "username", "password", "email", "gender", "gang") VALUES ($1, $2, $3, $4, $5, $6)`
_, err = db.Exec(sqlQuery, 1, "Ross8839", "rocky8839", "ross88399@hotmail.com", "Female", "Greengos")
if err != nil {
    fmt.Fprintf(os.Stdout, "Failed to query db")
    panic(err)
}
}

I expect that the above code isn't incorrect, as I had this working in my windows environment, but I don't want to use windows for development. This is all in my Linux environment, and since moving over... I have encountered this issue.

Below are the permissions for postgres user on database
