pgx also includes support for custom types implementing the database/sql.Scanner pgx also includes support for custom types implementing the database/sql.Scanner
and database/sql/driver.Valuer interfaces. and database/sql/driver.Valuer interfaces.
If pgx does cannot natively encode a type and that type is a renamed type (e.g.
type MyTime time.Time) pgx will attempt to encode the underlying type. While
this is usually desired behavior it can produce suprising behavior if one the
underlying type and the renamed type each implement database/sql interfaces and
the other implements pgx interfaces. It is recommended that this situation be
avoided by implementing pgx interfaces on the renamed type.
