Tom Lane eedb7d18fa Modify RelationGetBufferForTuple() so that we only do lseek and lock ... when we need to move to a new page; as long as we can insert the new tuple on the same page as before, we only need LockBuffer and not the expensive stuff. Also, twiddle bufmgr interfaces to avoid redundant lseeks in RelationGetBufferForTuple and BufferAlloc. Successive inserts now require one lseek per page added, rather than one per tuple with several additional ones at each page boundary as happened before. Lock contention when multiple backends are inserting in same table is also greatly reduced.		2001-05-12 19:58:28 +00:00
