Fix incorrect password transformation in

|

If a password string contained the byte value <literal>0x80</>, the
|

remainder of the password was ignored, causing the password to be much
|
||||
weaker than it appeared. With this fix, the rest of the string is
|
||||
properly included in the DES hash. Any stored password values that are
|
||||
affected by this bug will thus no longer match, so the stored values may
|
||||
need to be updated. (CVE-2012-2143)

8.4, you'd silently get possibly-wrong answers, since the value

weaker than it appeared. With this fix, the rest of the string is

properly included in the DES hash. Any stored password values that are

affected by this bug will thus no longer match, so the stored values may

8.4, you'd silently get possibly-wrong answers, since the value

However, if you use the <type>citext</> data type, and you upgraded

you should run <literal>CREATE EXTENSION citext FROM unpackaged</>

The same is necessary if you restore a dump from a pre-9.1 database

If you've already run the <command>CREATE EXTENSION</> command before

Make <filename>contrib/citext</>'s upgrade script fix collations of

Release 9.1.2 provided a fix for collations of <type>citext</> columns

and indexes in databases upgraded or reloaded from pre-9.1
|

installations, but that fix was incomplete: it neglected to handle arrays
|
||||
and domains over <type>citext</>. This release extends the module's
|
||||
upgrade script to handle these cases. As before, if you have already
|
||||
run the upgrade script, you'll need to run the collation update
|
||||
commands by hand instead. See the 9.1.2 release notes for more
|
||||
information about doing this.
