Sequencing of QueuedQuery responses

[kjplatz]

I intend on using the Batch interface to send a large number of SELECT statements to my Postgres DB (specifically using pgvector extensions). If I do something like

    batch := &pgx.Batch{}
    batch.Queue("Select foo from bar").Query( func(r Rows) error { /* callback function 1 */ })
    batch.Queue("Select foo2 from bar").Query( func(r Rows) error { /* callback function 2 */ })
    br := conn.SendBatch(batch)
    br.Close()

Are these two callback functions guaranteed to execute in the order they are specified, or will they execute in some nonspecified order?

They will execute in the order the queries are queued. i.e. they will execute in the order you expect.
