func updateSession(sid string, uid int) {

for example :
if it's a new session, it should insert or else it should update

queryString := INSERT INTO sessions(session_id, user_id)
SELECT $1::VARCHAR, $2
WHERE
NOT EXISTS (
SELECT session_id FROM sessions where session_id = $1
)`
_, err := database.Exec(queryString, sid, currUserId)
checkErrorAndExit(err, "insert")

_, err = database.Exec("UPDATE sessions SET user_id = $2 where session_id = $1", sid, currUserId)
checkErrorAndExit(err, "update")`
