This class represents a StartupPacket message of PostgreSQL protocol. This class represents the Parse message sent to PostgreSQL server. Represents a transaction to be made in a PostgreSQL database. This class cannot be inherited. Releases the unmanaged resources used by the NpgsqlTransaction and optionally releases the managed resources. Commits the database transaction. Rolls back a transaction from a pending state. Cancel the transaction without telling the backend about it. This is used to make the transaction go away when closing a connection. Gets the NpgsqlConnection object associated with the transaction, or a null reference if the transaction is no longer valid. The NpgsqlConnection object associated with the transaction. Specifies the IsolationLevel for this transaction. The IsolationLevel for this transaction. The default is ReadCommitted. Represent the frontend/backend protocol version. Represent the backend server version. Returns the string representation of this version in three place dot notation (Major.Minor.Patch). Server version major number. Server version minor number. Server version patch level number. This class provides many util methods to handle reading and writing of PostgreSQL protocol messages. This method takes a ProtocolVersion and returns an integer version number that the Postgres backend will recognize in a startup packet. This method takes a version string as returned by SELECT VERSION() and returns a valid version string ("7.2.2" for example). This is only needed when running protocol version 2. This does not do any validity checks. This method takes a version string ("7.4.1" for example) and produces the required integer version numbers (7, 4, and 1). Convert the beginning numeric part of the given string to Int32. For example: Strings "12345ABCD" and "12345.54321" would both be converted to int 12345. This method gets a C NULL terminated string from the network stream. It keeps reading a byte in each time until a NULL byte is returned. It returns the resultant string of bytes read. This string is sent from backend. This method gets a length terminated string from a network stream. It returns the resultant string of bytes read. This string is sent from backend. This method writes a C NULL terminated string to the network stream. It appends a NULL terminator to the end of the String. This method writes a C NULL terminated string limited in length to the backend server. It pads the string with null bytes to the size specified. Write a 32-bit integer to the given stream in the correct byte order. Read a 32-bit integer from the given stream in the correct byte order. Write a 16-bit integer to the given stream in the correct byte order. Read a 16-bit integer from the given stream in the correct byte order. Summary description for LargeObjectManager.

This way we don't have to load the basic type mappings for every connection. Find a NpgsqlNativeTypeInfo in the default types map that can handle objects of the given NpgsqlDbType. Find a NpgsqlNativeTypeInfo in the default types map that can handle objects of the given DbType. Find a NpgsqlNativeTypeInfo in the default types map that can handle objects of the given System.Type. This method is responsible to convert the string received from the backend to the corresponding NpgsqlType. The given TypeInfo is called upon to do the conversion. If no TypeInfo object is provided, no conversion is performed. Create the one and only native to backend type map. This map is used when formatting native data types to backend representations. This method creates (or retrieves from cache) a mapping between type and OID of all natively supported postgresql data types. This is needed as from one version to another, this mapping can be changed and so we avoid hardcoding them. NpgsqlTypeMapping containing all known data types. The mapping must be cloned before it is modified because it is cached; changes made by one connection may effect another connection. Attempt to map types by issuing a query against pg_type. This function takes a list of NpgsqlTypeInfo and attempts to resolve the OID field of each by querying pg_type. If the mapping is found, the type info object is updated (OID) and added to the provided NpgsqlTypeMapping object. NpgsqlConnector to send query through. Mapping object to add types too. List of types that need to have OID's mapped. Delegate called to convert the given backend data to its native representation. Delegate called to convert the given native data to its backand representation. Represents a backend data type.
