You might be wondering how to insert multiple rows into a table using Node Postgres. Most examples show adding only one row at a time. Some solutions recommend using a control flow library like async. But this technique is slow and inefficient because it uses too many connections or sends the queries one by one.

The view of docs will be in a similar manner to andnodejs.
