You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: db.go
    path of file: ./repos/kerkour.com/blog/2022/postgresql_insert_performance/go
    
    the code of the file until where you have to start completion: package main

import (
	"context"
	"fmt"

	"github.com/jackc/pgtype"
	"github.com/jackc/pgx/v4"
	"github.com/jackc/pgx/v4/pgxp
    
func dbCleanTable(ctx context.Context, pool *pgxpool.Pool, table string) (err error) {
	queryDelete := "DELETE FROM " + table
	queryVacuum := "VACUUM FULL " + table

	_, err = pool.Exec(ctx, queryDelete)
	if err != nil {
		return
	}

	_, err = pool.Exec(ctx, queryVacuum)
	if err != nil {
		return
	}

	return
