If the string it is having trouble with is "NaN" or "Infinity" then i have
a patch to Village to solve that (it makes NaN insert NULL in the database
and retriving NULL gives NaN instead of 0).  If it really is "blabla",
then perhaps you have one of the fields in project-schema.xml marked as a
string when it really is a integer in the database?

PostgreSQL does support NaN in the database, but it must be sent as 'NaN'
instead of NaN, which is what the JDBC driver sends it as (as it just does
.toString() on the value).  I have reported this bug to the PostgreSQL
mailing list, but it has yet to be fixed.

Neither MySQL or Microsoft SQl Server support NaN properly via JDBC
either, hence my patching Village to work around the problem.
