Architecture Reference Manual for ARMv8 B2.2.1 [1] For explicit memory effects generated from an Exception level the following rules apply: - A read that is generated by a load instruction that loads a single general-purpose register and is aligned to the size of the read in the instruction is single-copy atomic. - A write that is generated by a store instruction that stores a single general-purpose register and is aligned to the size of the write in the instruction is single-copy atomic.

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.
