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.

Other solutions recommend using a heavyweight ORM, but this might require a significant rewrite of your application.

A transaction contains any number of statements. At any point you can rollback if an error occurs or your logic fail conditions trigger.
