There is an updated release of my utils2_ak package available as of 1/30.
This update includes the following changes:

Myschema:
Shifted the implicit/explicit keyword to upper case for consistency.
Fixed a bug that was ignoring casts from or to built-in (non-UDT) types.

Dostats:
Fixed a bug in SET ISOLATION when executing immediately.
Fixed a bug in --drop-distributions.
Added --clean-distributions for cleaning out old distributions when only
specific tables are being processed. This can be used globally, but
--drop-distributions will tend to be faster.
Restricted --drop-distributions from being used with -t, -x or -i since it
would drop distributions from all tables and then only rebuild the
distributions for the specified tables. Thanks to Ashok Sharma for pointing
out these bugs.
