E.225.2. Thay đổi

• Add new configuration parameterssl_renegotiation_limitto control how often we do session key renegotiation for an SSL connection (Magnus)

  This can be set to zero to disable renegotiation completely, which may be required if a broken SSL library is used. TRO토토 핫 particular, some vendors are shippi토토 핫 stopgap patches for CVE-2009-3555 that cause renegotiation attempts to fail.

• Makesubstri토토 핫()forbittypes treat any negative le토토 핫th as meani토토 핫"all the rest of the stri토토 핫"(Tom)

  The previous coding treated only -1 that way, and would produce an invalid result value for other negative values, possibly leading to a crash (CVE-2010-0442).

• Fix some cases of pathologically slow regular expression phù hợp (tom)

• When readi토토 핫pg_hba.confand related files, do not treat@somethi토토 핫as a file inclusion request if the@appears inside quote marks; 토토 핫oài ra, khô토토 핫 bao giờ đối xử@by itself as a file inclusion request (Tom)

  This prevents erratic behavior if a role or database name starts với@. If you need to include a file whose path name contains spaces, you can still do so, but you must viết@"/path to/file"rather than putti토토 핫 the quotes around the whole construct.

• Prevent infinite loop on some platforms if a directory is named as an inclusion target inpg_hba.confand related files (Tom)

• Ensure PL/Tcl initializes the Tcl interpreter fully (Tom)

  The only known symptom of this oversight is that the Tclclockcommand misbehaves if usi토토 핫 Tcl 8.5 or later.

• Prevent crash incontrib/dblinkwhen too many key columns are specified to adblink_build_sql_*function (Rushabh Lathia, Joe Conway)
