* sync_method is renamed to wal_sync_method. * sync_method_options[] is renamed to wal_sync_method_options[]. * assign_xlog_sync_method() is renamed to assign_wal_sync_method(). * The names of the available synchronization methods are now prefixed with "WAL_SYNC_METHOD_" and have been moved into a WalSyncMethod enum. * PLATFORM_DEFAULT_SYNC_METHOD is renamed to PLATFORM_DEFAULT_WAL_SYNC_METHOD, and DEFAULT_SYNC_METHOD is renamed to DEFAULT_WAL_SYNC_METHOD. These more descriptive names help distinguish the code for wal_sync_method from the code for DataDirSyncMethod (e.g., the recovery_init_sync_method configuration parameter and the --sync-method option provided by several frontend utilities). This change also prevents name collisions between the aforementioned sets of code. Since this only improves the naming of internal identifiers, there should be no behavior change.

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.
