Mike,
Have a look at the PostgreSQLEXDIFieldValue hierarchy and the
>>buildTranslationsFromPostgres method on the class side of
PostgreSQLEXDISession. You might find that adding explicit support
for floats here would help.
Alternatively, or in addition, you could add a test to
PostgreSQLEXDITest which fails in a situation which demonstrates the
issue.
All the best,
Bruce
