I tried to reproduce bugs you described, but I was not able to model
the situation when database returns negative values (I was just not
able to insert values that cause overflow in database).

TypeConversionError is thrown when you assign BigDecimal to a column
that is not FBBigDecimalField (note, NUMERIC(p, s) with s == 0 is not
FBBigDecimalField, but FBLongField). Type conversion happens before
sending request to database. Therefore you do not get SQLException
with code 335544321 which is exception originated by database server.

Can you give any clue how to reproduce overflow error?

Thanks in advance,
