1673 This module should probably be renamed, since much of the functionality is
1674 of general use. It is not completely unlike Adapter::DBI (see below).
1676 Exported qsearch and qsearchs should be deprecated in favor of method calls
1677 (against an FS::Record object like the old search and searchs that qsearch
1678 and qsearchs were on top of.)
1680 The whole fields / hfields mess should be removed.
1682 The various WHERE clauses should be subroutined.
1684 table string should be deprecated in favor of DBIx::DBSchema::Table.
1686 No doubt we could benefit from a Tied hash. Documenting how exists / defined
1687 true maps to the database (and WHERE clauses) would also help.
1689 The ut_ methods should ask the dbdef for a default length.
1691 ut_sqltype (like ut_varchar) should all be defined
1693 A fallback check method should be provided which uses the dbdef.
1695 The ut_money method assumes money has two decimal digits.
1697 The Pg money kludge in the new method only strips `$'.
