This could be done by having Django's database interface catch the
error, and chain a new exception from that one:
try:
pgsql_cursor.execute(foo)
except pgsql.SpamException as exc:
error = DatabaseError(
"in {model_name}: {exc}".format(
exc=exc, model_name=fully_qualified_model_name))
raise error from exc
See PEP 3134 for the exception chaning syntax ‘raise foo from bar’
