  * New upstream bug fix release 8.1.17: (LP: #344688)
    - Prevent error recursion crashes when encoding conversion fails.
      This change extends fixes made in the last two minor releases for
      related failure scenarios. The previous fixes were narrowly
      tailored for the original problem reports, but we have now
      recognized that *any* error thrown by an encoding conversion
      function could potentially lead to infinite recursion while trying
      to report the error. The solution therefore is to disable
      translation and encoding conversion and report the plain-ASCII form
      of any error message, if we find we have gotten into a recursive
      error reporting situation.
    - Disallow "CREATE CONVERSION" with the wrong encodings for the
      specified conversion function. This prevents one possible scenario for
      encoding conversion failure. The previous change is a backstop to guard
      against other kinds of failures in the same area.
    - Fix core dump when to_char() is given format codes that are
      inappropriate for the type of the data argument.
    - Fix decompilation of CASE WHEN with an implicit coercion.
    - Fix possible misassignment of the owner of a TOAST table's rowtype.
      If "CLUSTER" or a rewriting variant of "ALTER TABLE" were executed
      by someone other than the table owner, the pg_type entry for the
      table's TOAST table would end up marked as owned by that someone.
      This caused no immediate problems, since the permissions on the
      TOAST rowtype aren't examined by any ordinary database operation.
      However, it could lead to unexpected failures if one later tried to
      drop the role that issued the command (in 8.1 or 8.2), or "owner of
      data type appears to be invalid" warnings from pg_dump after having
      done so (in 8.3).
    - Clean up PL/pgSQL error status variables fully at block exit.
      This is not a problem for PL/pgSQL itself, but the omission could
      cause the PL/pgSQL Debugger to crash while examining the state of a
      function.
    - Add MUST (Mauritius Island Summer Time) to the default list of
      known timezone abbreviations.
