The deserialization failed to ensure correct alignment, as it assumed it can simply point into the serialized value. The serialization however ignores alignment and copies just the significant bytes in order to make the result as small as possible. This caused failures on systems that are sensitive to mialigned addresses, like sparc, or with address sanitizer enabled. Fixed by copying the serialized data to ensure proper alignment. While at it, fix an issue with serialization on big endian machines, using the same store_att_byval/fetch_att trick as extended statistics.

PostgreSQL Database Management System ===================================== This directory contains the source code distribution of the PostgreSQL database management system. PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
