How to use RegisterDefaultPgType with connection Pool?

[stasvo]

As I understood type mappings can be registered with pgtype.Map.RegisterDefaultPgType.
And if I am not wrong in case of use *Conn (without pool) for register type possible to use this method: conn.TypeMap().RegisterDefaultPgType()
But in case of *pgxpool.Pool there no TypeMap() method, how possible to register type while use connection pool (*pgxpool.Pool)?

You can do type registration in an AfterConnect hook with pgxpool. See https://pkg.go.dev/github.com/jackc/pgx/v5@v5.3.1/pgxpool#Config.
