Problems with Data Types, High Severity (4)

	Change	Effect
1	Size of this class has been increased from 116 bytes to 124 bytes.	1) An object of this class can be allocated by the applications and old size will be hardcoded at the compile time. Call of any exported constructor will break the memory of neighboring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.

	Change	Effect
1	Size of this class has been increased from 36 bytes to 44 bytes.	1) An object of this class can be allocated by the applications and old size will be hardcoded at the compile time. Call of any exported constructor will break the memory of neighboring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.

Problems with Data Types, Medium Severity (16)

	Change	Effect
1	Size of field statement_ has been changed from 116 bytes to 124 bytes.	Previous accesses of applications and library functions to this field and fields at higher positions of the structure definition may be broken.

	Change	Effect
1	Field rowsAffectedBulk_ has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

Problems with Data Types, Low Severity (4)

	Change	Effect
1	Virtual method details::session_backend::get_next_sequence_value ( session&, std::string const&, long& ) has been overridden by postgresql_session_backend::get_next_sequence_value ( session&, std::string const&, long& ).	Method postgresql_session_backend::get_next_sequence_value ( session&, std::string const&, long& ) will be called instead of details::session_backend::get_next_sequence_value ( session&, std::string const&, long& ) by old applications.

44	postgresql_session_backend::make_rowid_backend	postgresql_session_backend::make_rowid_backend
48	postgresql_session_backend::make_blob_backend	postgresql_session_backend::make_blob_backend

	Change	Effect
1	The pointer level of field result_ has been decreased from 1 to 0.	The library functions will treat the value of this field as the lower-dimension array and will not read all elements. This may change the behavior of applications.
2	Type of field result_ has been changed from PGresult* to details::postgresql_result.	Replacement of the field data type may indicate a change in the semantic meaning of the field.

	Change	Effect
1	Field rowsAffectedBulk_ has been added to this type.	1) This field will not be initialized by old clients. 2) Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
