 pgsql/ ontrib/dbase/dbf.c ontrib/pg_resetxlog/ ...

CVSROOT:        /home/projects/pgsql/cvsroot
Module name:    pgsql

Modified files:
        contrib/dbase  : dbf.c
        contrib/pg_resetxlog: pg_resetxlog.c
        src/backend/access/transam: xlog.c
        src/backend/storage/file: fd.c
        src/backend/storage/smgr: md.c
        src/backend/utils/init: miscinit.c

Log message:
        Adjust WAL code so that checkpoints truncate the xlog at the previous
        checkpoint's redo pointer, not its undo pointer, per discussion in
        pghackers a few days ago.  No point in{*filter*} onto undo information
        until we have the ability to do something with it --- and this solves
        a rather large problem with log space for long-running transactions.
        Also, change all calls of write() to detect the case where write
        returned a count less than requested, but failed to set errno.
        Presume that this situation indicates ENOSPC, and give the appropriate
        error message, rather than a random message associated with the previous
        value of errno.
