* Add REGEX internationalization
* allow row re-use without vacuum, maybe?(Vadim)
-* Add word index for text fields, maybe with trigrams, i.e.:
- * ' (cat | dog) & ! fox ' meaning text has cat aor dog, but not fox
* Populate backend status area and write program to dump status data
* Add ALTER TABLE DROP/ALTER COLUMN feature
-* Allow INSERT INTO ... SELECT to convert column types
