Overview
jackc/pgx
is a PostgreSQL low-level, high performance driver and toolkit that exposes PostgreSQL-specific features such as LISTEN/NOTIFY and COPY. It also includes an adapter for the standard database/sql
package, but using database/sql
is optional. It understands PostgreSQL data types. jackc/pgx
is recommended when the application only targets PostgreSQL.
Installation
go get github.com/jackc/pgx/v5
