Minor fixes and improvements:

• Fixed function choose_range_partition_name() for 32-bit platforms;
• Removed BOM marks (caused broken builds on old compilers).

• Parallel SeqScan support;
• Re-implemented some of plpgsql functions in C;
• Implemented auto check constraints renaming for partitions;
• Added replace_hash_partition() function;
• SpawnPartitionsWorker is disabled by default (can be enabled with set_spawn_using_bgw() function);
• Improved planning process (fixed bugs with inlined SQL functions, stability fixes);
• Auto created partitions share the same owner. (parent table owner);
• Partition creation now requires INSERT permission on parent table.

• Fixed not working attach_range_partition() and add_range_partition() when relation is marked as ‘partitioned’ (via pathman_config) but has no children;
• Prevent pathman_process_utility_hook() from messing with other extensions, e.g. pg_stat_statements (issue #42);
• Enable partition creation for COPY FROM statement (can be switched off);
• Minor improvements and stability fixes.

New features and enhancements:

• PostgreSQL 9.6 support;
• Tablespace support (#11);
• COPY FROM/TO support for partitioned tables (only for UNIX-like systems);
• Improved FDW support (redirect inserted rows);
• User-defined callbacks on partition creation events (#22);
• Permissions improvements (owner can manage his partitions without being superuser);
• Fixed SELECT FOR SHARE / FOR UPDATE handling;
• Fixed SELECT ... WHERE partitioned_attribute IN (...) for RANGE partitioning;
• Fixed unique inner & outer nested loop plan generation (sometimes there would be unwanted extra rows);
• Improved pl/PgSQL API (stability & performance, #39);
• Improved RANGE partitioning for domains and some other types.

Fix wrong check constraint naming (function build_check_constraint_name_internal()).

The prototype features RuntimeAppend & RuntimeMergeAppend custom nodes capable of discarding useless partition scans dynamically at runtime. This version is now deprecated.

This release contains various bugfixes and improvements, such as reworked partitioning info cache, concurrent partitioning and PartitionFilter custom node (drop-in replacement for INSERT triggers).
