There is no benefit in + using CONCURRENTLY for a temporary table anyway, + since other sessions cannot access the table, making the extra + processing pointless. + + + + + + + Fix possible failure when resetting expression indexes on temporary + tables that are marked ON COMMIT DELETE ROWS + (Tom Lane) + + + + + + + Fix handling of deleted pages in GIN indexes (Alexander Korotkov) + + + + Avoid possible deadlocks, incorrect updates of a deleted page's + state, and failure to traverse through a recently-deleted page. + + + + + + + Fix possible crash with a SubPlan (sub-SELECT) + within a multi-row VALUES list (Tom Lane) + + + + + + + Fix unlikely crash with pass-by-reference aggregate transition + states (Andres Freund, Teodor Sigaev) + + + + + + + Improve error reporting in to_date() + and to_timestamp() + (Tom Lane, Álvaro Herrera) + + + + Reports about incorrect month or day names in input strings could + truncate the input in the middle of a multi-byte character, leading + to an improperly encoded error message that could cause follow-on + failures. Truncate at the next whitespace instead. + + + + + + + Fix off-by-one result for EXTRACT(ISOYEAR + FROM timestamp) for BC dates + (Tom Lane) + + + + + + + Avoid stack overflow in information_schema views + when a self-referential view exists in the system catalogs + (Tom Lane) + + + + A self-referential view can't work; it will always result in + infinite recursion. We handled that situation correctly when + trying to execute the view, but not when inquiring whether it is + automatically updatable. + + + + + + + Improve performance of hash joins with very large inner relations + (Thomas Munro) + + + + + + + Fix edge-case crashes and misestimations in selectivity calculations + for the <@ and @> range + operators (Michael Paquier, Andrey Borodin, Tom Lane) + + + + + + + Improve error reporting for attempts to use automatic updating of + views with conditional INSTEAD rules (Dean Rasheed) + + + + This has never been supported, but previously the error was thrown + only at execution time, so that it could be masked by planner errors. + + + + + + + Prevent a composite type from being included in itself indirectly + via a range type (Tom Lane, Julien Rouhaud) + + + + + + + Fix error reporting for index expressions of prohibited types + (Amit Langote) + + + + + + + Fix dumping of views that contain only a VALUES + list to handle cases where a view output column has been renamed + (Tom Lane) + + + + + + + Allow libpq to parse all GSS-related + connection parameters even when the GSSAPI code hasn't been compiled + in (Tom Lane) + + + + This makes the behavior similar to our SSL support, where it was + long ago deemed to be a good idea to always accept all the related + parameters, even if some are ignored or restricted due to lack of + the feature in a particular build. + + + + + + + Fix incorrect handling of %b + and %B format codes + in ecpg's + PGTYPEStimestamp_fmt_asc() function + (Tomas Vondra) + + + + Due to an off-by-one error, these codes would print the wrong month + name, or possibly crash. + + + + + + + Fix + parallel pg_dump/pg_restore + to more gracefully handle failure to create worker processes + (Tom Lane) + + + + + + + Prevent possible crash or lockup when attempting to terminate a + parallel pg_dump/pg_restore + run via a signal (Tom Lane) + + + + + + + In pg_upgrade, look inside arrays and + ranges while searching for non-upgradable data types in tables + (Tom Lane) + + + + + + + In contrib/dict_int, + reject maxlen settings less than one + (Tomas Vondra) + + + + This prevents a possible crash with silly settings for that parameter. + + + + + + + Disallow NULL category values + in contrib/tablefunc's + crosstab() function (Joe Conway) + + + + This case never worked usefully, and it would crash on some + platforms. + + + + + + + Mark some timeout and statistics-tracking GUC variables + as PGDLLIMPORT, to allow extensions to access + them on Windows (Pascal Legrand) + + + + This applies to + idle_in_transaction_session_timeout, + lock_timeout, + statement_timeout, + track_activities, + track_counts, and + track_functions. + + + + + + + Fix race condition that led to delayed delivery of interprocess + signals on Windows (Amit Kapila) + + + + This caused visible timing oddities in NOTIFY, + and perhaps other misbehavior. + + + + + + + On Windows, retry a few times after + an ERROR_ACCESS_DENIED file access failure + (Alexander Lakhin, Tom Lane) + + + + This helps cope with cases where a file open attempt fails because + the targeted file is flagged for deletion but not yet actually gone. + pg_ctl, for example, frequently failed + with such an error when probing to see if the postmaster had shut + down yet. + + + + + + + + Release 9.4.25
