- Fix data encoding error in hungarian.stop
- Prevent foreign tables from being created with OIDS when default_with_oids is true

- Clear pg_stat_activity.xact_start during PREPARE TRANSACTION
- Fix REASSIGN OWNED to not fail for text search objects
- Prevent pg_class.relminmxid values from going backwards during VACUUM FULL
- Reduce indentation in rule/view dumps to improve readability and avoid excessive whitespace
- Fix dumping of rules/views when subsequent addition of a column has resulted in multiple input columns matching a USING specification
- Repair view printing for some cases involving functions in FROM that return a composite type containing dropped columns
- Block signals during postmaster startup
- Fix client host name lookup when processing pg_hba.conf entries that specify host names instead of IP addresses
- Allow the root user to use postgres -C variable and postgres --describe-config
- Secure Unix-domain sockets of temporary postmasters started during make check
- Fix tablespace creation WAL replay to work on Windows
- Fix detection of socket creation failures on Windows
- On Windows, allow new sessions to absorb values of PGC_BACKEND parameters (such as log_connections) from the configuration file
- Properly quote executable path names on Windows
- Fix linking of libpython on OS X
- Avoid buffer bloat in libpq when the server consistently sends data faster than the client can absorb it
- Ensure that LDAP lookup attempts in libpq time out as intended
- Fix ecpg to do the right thing when an array of char * is the target for a FETCH statement returning more than one row, as well as some other array-handling fixes
- Fix pg_dump to cope with a materialized view that depends on a table's primary key
- Fix parsing of pg_dumpall's -i switch
- Fix pg_restore's processing of old-style large object comments
- Fix pg_upgrade for cases where the new server creates a TOAST table but the old version did not
- In pg_upgrade, preserve pg_database.datminmxid and pg_class.relminmxid values from the old cluster, or insert reasonable values when upgrading from pre-9.3; also defend against unreasonable values in the core server
- Prevent contrib/auto_explain from changing the output of a user's EXPLAIN
- Fix query-lifespan memory leak in contrib/dblink
- In contrib/pgcrypto functions, ensure sensitive information is cleared from stack variables before returning
- Prevent use of already-freed memory in contrib/pgstattuple's pgstat_heap()
- In contrib/uuid-ossp, cache the state of the OSSP UUID library across calls
- Update time zone data files to tzdata release 2014e for DST law changes in Crimea, Egypt, and Morocco.
