crdbpgx is a wrapper around the logic for issuing SQL transactions which performs retries (as required by CockroachDB) when using github.com/jackc/pgx in standalone-library mode. pgx versions below v4 are not supported.

Note: use crdbpgxv5 for pgx/v5 support

If you're using pgx just as a driver for the standard database/sql package, use the parent crdb package instead.
