    path of file: ./repos/plumber/vendor/github.com/jackc/pgx/pgtype
    
    the code of the file until where you have to start completion: package pgtype

import (
	"database/sql/driver"
	"encoding/binary
    
func (dst *Float4Array) Get() interface{} {
	switch dst.Status {
	case Present:
		return dst
	case Null:
