Functions

func RegisterAll 

func RegisterAll(ctx context.Context, conn *pgx.Conn) ([]*Type, error)

RegisterAll registers both integer types and their associated variants.

This function invokes RegisterTypes to register the main integer types (uint2, uint4, uint8, uint16 and int16) and subsequently registers their variants (array, range, multirange) in the TypeMap of pgx.Conn by calling RegisterDefaultPgTypeVariants.

It returns a slice of pointers to the registered Type structs. If an error occurs during the registration process, it returns nil along with the error.

The returned types can be used to register them on new connections without issuing actual database queries. For example, you can use the following code: 

	conn.TypeMap().RegisterTypes(regTypes)
 types.RegisterDefaultPgTypeVariants(conn.TypeMap())

Note that the uniqueness of type OIDs is guaranteed only within a single server and a single database on that server. Consequently, OIDs may conflict across different databases or servers.

func RegisterDefaultPgTypeVariants 

func RegisterDefaultPgTypeVariants(tMap *Map)

func RegisterTypes 

func RegisterTypes(ctx context.Context, conn *pgx.Conn) ([]*Type, error)

RegisterTypes registers all integer types (uint2, uint4, uint8, uint16 and int16) at once.

It returns a slice of pointers to the registered Type structs corresponding to these types.

The returned types can be used to register them on new connections without issuing actual database queries. For example, you can use the following code: 

conn.TypeMap().RegisterTypes(types)

Note that the uniqueness of type OIDs is guaranteed only within a single server and a single database on that server. Consequently, OIDs may conflict across different databases or servers.

If there is an error while loading the types, it will be returned, along with a nil slice.
