Subject Re: PostgreSQL BIT/Boolean madness
Date Wed, 08 Jan 2014 03:31:30 GMT
It isn't clear to me what is going on, but with the DBDictionary you can
change the type of column that boolean / bit field types are mapped to.
Perhaps you can change the bitTypeName / booleanTypeName to see if you can
get something working? To change these values you can change the type to
set the property openjpa.jdbc.DBDictionary=postgres(bitTypeName="BIT").
