<title>Migration to Version 9.3.6</title>
22
A dump/restore is not required for those running 9.3.X.
26
However, if you are a Windows user and are using the <quote>Norwegian
27
(Bokmål)</> locale, manual action is needed after the upgrade to
28
replace any <quote>Norwegian (Bokmål)_Norway</> locale names stored
29
in <productname>PostgreSQL</> system catalogs with the plain-ASCII
30
alias <quote>Norwegian_Norway</>. For details see
31
<ulink url="http://wiki.postgresql.org/wiki/Changes_To_Norwegian_Locale"></>
35
Also, if you are upgrading from a version earlier than 9.3.5,
36
see <xref linkend="release-9-3-5">.

Fix buffer overruns in <function>to_char()</>
70
When <function>to_char()</> processes a numeric formatting template
71
calling for a large number of digits, <productname>PostgreSQL</>
72
would read past the end of a buffer. When processing a crafted
73
timestamp formatting template, <productname>PostgreSQL</> would write
74
past the end of a buffer. Either case could crash the server.
75
We have not ruled out the possibility of attacks that lead to
76
privilege escalation, though they seem unlikely.

Fix buffer overrun in replacement <function>*printf()</> functions
98
<productname>PostgreSQL</> includes a replacement implementation
99
of <function>printf</> and related functions. This code will overrun
100
a stack buffer when formatting a floating point number (conversion
101
specifiers <literal>e</>, <literal>E</>, <literal>f</>, <literal>F</>,
102
<literal>g</> or <literal>G</>) with requested precision greater than
103
about 500. This will crash the server, and we have not ruled out the
104
possibility of attacks that lead to privilege escalation.
105
A database user can trigger such a buffer overrun through
106
the <function>to_char()</> SQL function. While that is the only
107
affected core <productname>PostgreSQL</> functionality, extension
108
modules that use printf-family functions may be at risk as well.
112
This issue primarily affects <productname>PostgreSQL</> on Windows.
113
<productname>PostgreSQL</> uses the system implementation of these
114
functions where adequate, which it is on other modern platforms.

Fix buffer overruns in <filename>contrib/pgcrypto</>
139
(Marko Tiikkaja, Noah Misch)
143
Errors in memory size tracking within the <filename>pgcrypto</>
144
module permitted stack buffer overruns and improper dependence on the
145
contents of uninitialized memory. The buffer overrun cases can
146
crash the server, and we have not ruled out the possibility of
147
attacks that lead to privilege escalation.

Fix possible loss of frontend/backend protocol synchronization after
170
If any error occurred while the server was in the middle of reading a
171
protocol message from the client, it could lose synchronization and
172
incorrectly try to interpret part of the message's data as a new
173
protocol message. An attacker able to submit crafted binary data
174
within a command parameter might succeed in injecting his own SQL
175
commands this way. Statement timeout and query cancellation are the
176
most likely sources of errors triggering this scenario. Particularly
177
vulnerable are applications that use a timeout and also submit
178
arbitrary user-crafted data as binary query parameters. Disabling
179
statement timeout will reduce, but not eliminate, the risk of
180
exploit. Our thanks to Emil Lenngren for reporting this issue.

Fix information leak via constraint-violation error messages
202
Some server error messages show the values of columns that violate
203
a constraint, such as a unique constraint. If the user does not have
204
<literal>SELECT</> privilege on all columns of the table, this could
205
mean exposing values that the user should not be able to see. Adjust
206
the code so that values are displayed only when they came from the SQL
207
command or could be selected by the user.

In <function>numeric_recv()</>, truncate away any fractional digits

580
A <type>numeric</> value's display scale (<literal>dscale</>) should

never be less than the number of nonzero fractional digits; but
582
apparently there's at least one broken client application that

584
This leads to strange behavior since the extra digits are taken into

587
digits on receipt, so that the value is indeed what it prints as.

Change <quote>pgstat wait timeout</> warning message to be LOG level,
1005

1009
This message was originally thought to be essentially a can't-happen
1010
case, but it occurs often enough on our slower buildfarm members to be
1011
a nuisance. Reduce it to LOG level, and expend a bit more effort on
1012
the wording: it now reads <quote>using stale statistics instead of
1013
current ones because stats collector is not responding</>.

Fix <application>psql</>'s <command>\s</> command to work nicely with
1182
libedit, and add pager support (Stepan Rutz, Tom Lane)
1186
When using libedit rather than readline, <command>\s</> printed the
1187
command history in a fairly unreadable encoded format, and on recent
1188
libedit versions might fail altogether. Fix that by printing the
1189
history ourselves rather than having the library do it. A pleasant
1190
side-effect is that the pager is used if appropriate.
1194
This patch also fixes a bug that caused newline encoding to be applied
1195
inconsistently when saving the command history with libedit.
1196
Multiline history entries written by older <application>psql</>
1197
versions will be read cleanly with this patch, but perhaps not
1198
vice versa, depending on the exact libedit versions involved.

1619
The previous over-conservative marking was immaterial in normal use,
1620
but could cause optimization problems or rejection of valid index

expression definitions. Since the consequences are not large, we've
1622
just adjusted the function definitions in the extension modules'

scripts, without changing version numbers.

Support time zone abbreviations that change UTC offset from time to
1795
Previously, <productname>PostgreSQL</> assumed that the UTC offset
1796
associated with a time zone abbreviation (such as <literal>EST</>)
1797
never changes in the usage of any particular locale. However this
1798
assumption fails in the real world, so introduce the ability for a
1799
zone abbreviation to represent a UTC offset that sometimes changes.
1800
Update the zone abbreviation definition files to make use of this
1801
feature in timezone locales that have changed the UTC offset of their
1802
abbreviations since 1970 (according to the IANA timezone database).
1803
In such timezones, <productname>PostgreSQL</> will now associate the
1804
correct UTC offset with the abbreviation depending on the given date.

Update time zone data files to <application>tzdata</> release 2015a.
1861
The IANA timezone database has adopted abbreviations of the form
1862
<literal>A<replaceable>x</>ST</literal>/<literal>A<replaceable>x</>DT</literal>
1863
for all Australian time zones, reflecting what they believe to be
1864
current majority practice Down Under. These names do not conflict
1865
with usage elsewhere (other than ACST for Acre Summer Time, which has
1866
been in disuse since 1994). Accordingly, adopt these names into
1867
our <quote>Default</> timezone abbreviation set.
1868
The <quote>Australia</> abbreviation set now contains only CST, EAST,
1869
EST, SAST, SAT, and WST, all of which are thought to be mostly
1870
historical usage. Note that SAST has also been changed to be South
1871
Africa Standard Time in the <quote>Default</> abbreviation set.
1875
Also, add zone abbreviations SRET (Asia/Srednekolymsk) and XJT
1876
(Asia/Urumqi), and use WSST/WSDT for western Samoa. Also, there were
1877
DST law changes in Chile, Mexico, the Turks & Caicos Islands
1878
(America/Grand_Turk), and Fiji. There is a new zone
1879
Pacific/Bougainville for portions of Papua New Guinea. Also, numerous
1880
corrections for historical (pre-1970) time zone data.
