Bulk Inserts #2254

What do you want to change?

I would like to use queries like

INSERT INTO books(id, name) VALUES
(NULL, 'Notebook'),
(NULL, 'MacBook'),
(NULL, 'BookBook')
..;

We have support for COPY here, but it's not as flexible or as easy to use as the above syntax. Also, the above syntax allows for ON CONFLICT(id) UPDATE name = EXCLUDED.name, which is great for bulk updates / upserts.

The generated Go code should take a list of Param objects as input. I'm not quite sure how the SQL template should look, but maybe something like

-- name: BulkInsertBooks :bulk
INSERT INTO books(id, name) VALUES @bulkBookRows;

What database engines need to be changed?

PostgreSQL

What programming language backends need to be changed?

Go
