      Allow maximum number of backends to be set at configure time · e77b630c
      Tom Lane authored
      (--with-maxbackends).  Add a postmaster switch (-N backends) that allows
      the limit to be reduced at postmaster start time.  (You can't increase it,
      sorry to say, because there are still some fixed-size arrays.)
      Grab the number of semaphores indicated by min(MAXBACKENDS, -N) at
      postmaster startup, so that this particular form of bogus configuration
      is exposed immediately rather than under heavy load.

      lock.patch
      
              I have rewritten lock.c cleaning up the code and adding better
              assert checking I have also added some fields to the lock and
              xid tags for better support of user locks. There is also a new
              function which returns an array of pids owning a lock.
              I'm using this code from over six months and it works fine.

      Patch from Massimo Dal Zotto <dz@cs.unitn.it> · fb70587c
      Marc G. Fournier authored
      The following patches add to the backend a new debugging flag -K which prints
      a debug trace of all locking operations on user relations (those with oid
      greater than 20000). The code is compiled only if LOCK_MGR_DEBUG is defined,
      so the patch should be harmless if not explicitly enabled.
      I'm using the code to trace deadlock conditions caused by application queries
      using the command "$POSTMASTER -D $PGDATA -o '-d 1 -K 1'.
      The patches are for version 6.0 dated 970126.
