Let’s talk about 2 problems in this post.

batch insert in Postgres
batch insert in SQLC (with Golang)

To simplify, we will use an users table with 4 fields: id(text, primary key), name(text), created_at and updated_at. The insert data can be generated with pg-batch-play tool.

# generate 1M users data in SQL format with single INSERT command

go run main.go genbatchcreateuser -s 1000000 -f sql -t singular

Besides, we will also use psql tool to observe, let’s enable the timing option.
