FWIW, I can initdb --- that seems fine --- but the regression tests spew
lots of small fragments. What I suspect is that the bufmgr is
occasionally returning the wrong buffer :-(
regression.diffs attached. Also, "grep TRAP postmaster.log" shows
this is the cause of the coredump midway through:
TRAP: FailedAssertion("!(( (&(cdb_replace->buf_tag))->rnode.tblNode == (&(buf->tag))->rnode.tblNode &&
(&(cdb_replace->buf_tag))->rnode.relNode== (&(buf->tag))->rnode.relNode && (&(cdb_replace->buf_tag))->blockNum ==
(&(buf->tag))->blockNum))", File: "freelist.c", Line: 610)
Note this is with a serial test (make installcheck). Chris' very
different-looking results may be because he was doing parallel tests;
or there might be something else involved.
