What's new in this version:

- Fix infinite loops and buffer-overrun problems in regular expressions (Tom Lane)
- Very large character ranges in bracket expressions could cause infinite loops in some cases, and memory overwrites in other cases. (CVE-2016-0773)
- Fix an oversight that caused hash joins to miss joining to some tuples of the inner relation in rare cases (Tomas Vondra, Tom Lane)
- Avoid pushdown of HAVING clauses when grouping sets are used (Andrew Gierth)
- Fix deparsing of ON CONFLICT arbiter WHERE clauses (Peter Geoghegan)
- Make %h and %r escapes in log_line_prefix work for messages emitted due to log_connections (Tom Lane)
- Previously, %h/%r started to work just after a new session had emitted the "connection received" log message; now they work for that message too.
- Avoid leaking a token handle during SSPI authentication (Christian Ullrich)
- Fix psql's det command to interpret its pattern argument the same way as other d commands with potentially schema-qualified patterns do (Reece Hart)
- In pg_ctl on Windows, check service status to decide where to send output, rather than checking if standard output is a terminal (Michael Paquier)
- Fix assorted corner-case bugs in pg_dump's processing of extension member objects (Tom Lane)
- Fix improper quoting of domain constraint names in pg_dump (Elvis Pranskevichus)
- Make pg_dump mark a view's triggers as needing to be processed after its rule, to prevent possible failure during parallel pg_restore (Tom Lane)
- Install guards in pgbench against corner-case overflow conditions during evaluation of script-specified division or modulo operators (Fabien Coelho, Michael Paquier)
- Suppress useless warning message when pg_receivexlog connects to a pre-9.4 server (Marco Nenciarini)
- Avoid dump/reload problems when using both plpython2 and plpython3 (Tom Lane)
- In principle, both versions of PL/Python can be used in the same database, though not in the same session (because the two versions of libpython cannot safely be used concurrently). However, pg_restore and pg_upgrade both do things that can fall foul of the same-session restriction. Work around that by changing the timing of the check.
- Fix PL/Python regression tests to pass with Python 3.5 (Peter Eisentraut)
- Prevent certain PL/Java parameters from being set by non-superusers (Noah Misch)
- This change mitigates a PL/Java security bug (CVE-2016-0766), which was fixed in PL/Java by marking these parameters as superuser-only. To fix the security hazard for sites that update PostgreSQL more frequently than PL/Java, make the core code aware of them also.
- Fix ecpg-supplied header files to not contain comments continued from a preprocessor directive line onto the next line (Michael Meskes)
- Such a comment is rejected by ecpg. It's not yet clear whether ecpg itself should be changed.
- Fix hstore_to_json_loose()'s test for whether an hstore value can be converted to a JSON number (Tom Lane)
- Previously this function could be fooled by non-alphanumeric trailing characters, leading to emitting syntactically-invalid JSON.
- In contrib/postgres_fdw, fix bugs triggered by use of tableoid in data-modifying commands (Etsuro Fujita, Robert Haas)
- Fix ill-advised restriction of NAMEDATALEN to be less than 256 (Robert Haas, Tom Lane)
- Improve reproducibility of build output by ensuring filenames are given to the linker in a fixed order (Christoph Berg)
- This avoids possible bitwise differences in the produced executable files from one build to the next.
- Ensure that dynloader.h is included in the installed header files in MSVC builds (Bruce Momjian, Michael Paquier)
- Update time zone data files to tzdata release 2016a for DST law changes in Cayman Islands, Metlakatla, and Trans-Baikal Territory (Zabaykalsky Krai), plus historical corrections for Pakistan.
