      Widen xl_len field of XLogRecord header to 32 bits, so that we'll have · 0ffe11ab

      a more tolerable limit on the number of subtransactions or deleted files
      in COMMIT and ABORT records.  Buy back the extra space by eliminating the
      xl_xact_prev field, which isn't being used for anything and is rather
      unlikely ever to be used for anything.
      This does not force initdb, but you do need to do pg_resetxlog if you
      want to upgrade an existing 8.0 installation without initdb.

      Introduce local hash table for lock state, as per recent proposal. · 1785aceb
      Tom Lane 提交于
      PROCLOCK structs in shared memory now have only a bitmask for held
      locks, rather than counts (making them 40 bytes smaller, which is a
      good thing).  Multiple locks within a transaction are counted in the
      local hash table instead, and we have provision for tracking which
      ResourceOwner each count belongs to.  Solves recently reported problem
      with memory leakage within long transactions.
