+ Release 8.4.17
+
+
+ Release Date
+ 2013-04-04
+
+
+
+ This release contains a variety of fixes from 8.4.16.
+ For information about new features in the 8.4 major release, see
+ .
+
+
+
+ Migration to Version 8.4.17
+
+
+ A dump/restore is not required for those running 8.4.X.
+
+
+
+ However, this release corrects several errors in management of GiST
+ indexes. After installing this update, it is advisable to
+ REINDEX any GiST indexes that meet one or more of the
+ conditions described below.
+
+
+
+ Also, if you are upgrading from a version earlier than 8.4.10,
+ see the release notes for 8.4.10.

+
+ Changes
+
+
+
+
+
+ Reset OpenSSL randomness state in each postmaster child process
+ (Marko Kreen)
+
+
+
+ This avoids a scenario wherein random numbers generated by
+ contrib/pgcrypto functions might be relatively easy for
+ another database user to guess. The risk is only significant when
+ the postmaster is configured with ssl = on
+ but most connections don't use SSL encryption. (CVE-2013-1900)
+
+
+
+
+
+ Fix GiST indexes to not use fuzzy geometric comparisons when
+ it's not appropriate to do so (Alexander Korotkov)
+
+
+
+ The core geometric types perform comparisons using fuzzy
+ equality, but gist_box_same must do exact comparisons,
+ else GiST indexes using it might become inconsistent. After installing
+ this update, users should REINDEX any GiST indexes on
+ box, polygon, circle, or point
+ columns, since all of these use gist_box_same.
+
+
+
+
+
+ Fix erroneous range-union and penalty logic in GiST indexes that use
+ contrib/btree_gist for variable-width data types, that is
+ text, bytea, bit, and numeric
+ columns (Tom Lane)
+
+
+
+ These errors could result in inconsistent indexes in which some keys
+ that are present would not be found by searches, and also in useless
+ index bloat. Users are advised to REINDEX such indexes
+ after installing this update.
+
+
+
+
+
+ Fix bugs in GiST page splitting code for multi-column indexes
+ (Tom Lane)
+
+
+
+ These errors could result in inconsistent indexes in which some keys
+ that are present would not be found by searches, and also in indexes
+ that are unnecessarily inefficient to search. Users are advised to
+ REINDEX multi-column GiST indexes after installing this
+ update.
+
+
+
+
+
+ Fix infinite-loop risk in regular expression compilation (Tom Lane,
+ Don Porter)
+
+
+
+
+
+ Fix potential null-pointer dereference in regular expression compilation
+ (Tom Lane)
+
+
+
+
+
+ Fix to_char() to use ASCII-only case-folding rules where
+ appropriate (Tom Lane)
+
+
+
+ This fixes misbehavior of some template patterns that should be
+ locale-independent, but mishandled I and
+ i in Turkish locales.
+
+
+
+
+
+ Fix unwanted rejection of timestamp 1999-12-31 24:00:00
+ (Tom Lane)
+
+
+
+
+
+ Remove useless picksplit doesn't support secondary split log
+ messages (Josh Hansen, Tom Lane)
+
+
+
+ This message seems to have been added in expectation of code that was
+ never written, and probably never will be, since GiST's default
+ handling of secondary splits is actually pretty good. So stop nagging
+ end users about it.
+
+
+
+
+
+ Fix possible failure to send a session's last few transaction
+ commit/abort counts to the statistics collector (Tom Lane)
+
+
+
+
+
+ Eliminate memory leaks in PL/Perl's spi_prepare() function
+ (Alex Hunsaker, Tom Lane)
+
+
+
+
+
+ Fix pg_dumpall to handle database names containing
+ = correctly (Heikki Linnakangas)
+
+
+
+
+
+ Avoid crash in pg_dump when an incorrect connection
+ string is given (Heikki Linnakangas)
+
+
+
+
+
+ Ignore invalid indexes in pg_dump (Michael Paquier)
+
+
+
+ Dumping invalid indexes can cause problems at restore time, for example
+ if the reason the index creation failed was because it tried to enforce
+ a uniqueness condition not satisfied by the table's data. Also, if the
+ index creation is in fact still in progress, it seems reasonable to
+ consider it to be an uncommitted DDL change, which
+ pg_dump wouldn't be expected to dump anyway.
+
+
+
+
+
+ Fix contrib/pg_trgm's similarity() function
+ to return zero for trigram-less strings (Tom Lane)
+
+
+
+ Previously it returned NaN due to internal division by zero.
+
+
+
+
+
+ Update time zone data files to tzdata release 2013b
+ for DST law changes in Chile, Haiti, Morocco, Paraguay, and some
+ Russian areas. Also, historical zone data corrections for numerous
+ places.
+
+
+
+ Also, update the time zone abbreviation files for recent changes in
+ Russia and elsewhere: CHOT, GET,
+ IRKT, KGT, KRAT, MAGT,
+ MAWT, MSK, NOVT, OMST,
+ TKT, VLAT, WST, YAKT,
+ YEKT now follow their current meanings, and
+ VOLT (Europe/Volgograd) and MIST
+ (Antarctica/Macquarie) are added to the default abbreviations list.
