If the original data is later + deleted, it would lead to errors like missing chunk number 0 + for toast value ... when the now-dangling pointer is used. + + + + + + Fix record type has not been registered failures with + whole-row references to the output of Append plan nodes (Tom Lane) + + + + + + Fix possible crash when invoking a user-defined function while + rewinding a cursor (Tom Lane) + + + + + + Fix query-lifespan memory leak while evaluating the arguments for a + function in FROM (Tom Lane) + + + + + + Fix session-lifespan memory leaks in regular-expression processing + (Tom Lane, Arthur O'Dwyer, Greg Stark) + + + + + + Fix data encoding error in hungarian.stop (Tom Lane) + + + + + + Fix liveness checks for rows that were inserted in the current + transaction and then deleted by a now-rolled-back subtransaction + (Andres Freund) + + + + This could cause problems (at least spurious warnings, and at worst an + infinite loop) if CREATE INDEX or CLUSTER were + done later in the same transaction. + + + + + + Clear pg_stat_activity.xact_start + during PREPARE TRANSACTION (Andres Freund) + + + + After the PREPARE, the originating session is no longer in + a transaction, so it should not continue to display a transaction + start time. + + + + + + Fix REASSIGN OWNED to not fail for text search objects + (Álvaro Herrera) + + + + + + Block signals during postmaster startup (Tom Lane) + + + + This ensures that the postmaster will properly clean up after itself + if, for example, it receives SIGINT while still + starting up. + + + + + + Secure Unix-domain sockets of temporary postmasters started during + make check (Noah Misch) + + + + Any local user able to access the socket file could connect as the + server's bootstrap superuser, then proceed to execute arbitrary code as + the operating-system user running the test, as we previously noted in + CVE-2014-0067. This change defends against that risk by placing the + server's socket in a temporary, mode 0700 subdirectory + of /tmp. The hazard remains however on platforms where + Unix sockets are not supported, notably Windows, because then the + temporary postmaster must accept local TCP connections. + + + + A useful side effect of this change is to simplify + make check testing in builds that + override DEFAULT_PGSOCKET_DIR. Popular non-default values + like /var/run/postgresql are often not writable by the + build user, requiring workarounds that will no longer be necessary. + + + + + + On Windows, allow new sessions to absorb values of PGC_BACKEND + parameters (such as ) from the + configuration file (Amit Kapila) + + + + Previously, if such a parameter were changed in the file post-startup, + the change would have no effect. + + + + + + Properly quote executable path names on Windows (Nikhil Deshpande) + + + + This oversight could cause initdb + and pg_upgrade to fail on Windows, if the installation + path contained both spaces and @ signs. + + + + + + Fix linking of libpython on OS X (Tom Lane) + + + + The method we previously used can fail with the Python library + supplied by Xcode 5.0 and later. + + + + + + Avoid buffer bloat in libpq when the server + consistently sends data faster than the client can absorb it + (Shin-ichi Morita, Tom Lane) + + + + libpq could be coerced into enlarging its input buffer + until it runs out of memory (which would be reported misleadingly + as lost synchronization with server).
