I missing following in the doc:

• Concrete complete examples how to register custom composit types and enum and how to register it bulletproof in ConnInfo in AfterConnect.

type MyEnumTypeString string
// ...

type MySimpleCompTypeStruct struct {
   A string
   B string
}
// ...

• How exactly pgtype.DataType, pgtype.Value, pgtype.ValueType and my concrete go type I want to use (e.g. MyEnumTypeString, MySimpleCompTypeStruct) works together, how register it that it works smoothly in exec/query params but als rows result set (so automatic conversion of MySimpleCompTypeStruct and MyEnumTypeString in row.Values()). At best the example should be without pgtype.Status. A more common and implementation are simple nillable params without own status logic - so similar to the pgtype.zeronull package.

• A decision tree how Preferred methods, Binary codec methods, Text codec methods, ScanValuer, format code in query params, String method, and default is used - in query params and row.Values (auto type creation).

TODO: i must maybe clearify this issue but created it already because it took lot of time to understand the working of the typesystem
