Kristian Waagan updated DERBY-4937:
-----------------------------------

    Attachment: derby-4937-1b-explicit_update_stats.diff

Attaching patch 1b (formatting change only).

If you apply this patch now, calls to SYS_CS.UPDATE_STATISTICS will use the new daemon code
committed in DERBY-4936.

> Implement SYSCS_UTIL.UPDATE_STATISTICS by having the ALTER TABLE code use the new istat
daemon in explicit mode.
> Doing this will allow for a period of limited exposure before the background mode of
the daemon is enabled, and it will verify that the code generating the index statistics is
working.
