"""
Some versions of Oracle -- we've seen this on 11.2.0.1 and suspect
it goes back -- have a weird bug where, when an integer column is
defined with a default, its precision is later reported on introspection
as 0, regardless of the real precision. For Django introspection, this
means that such columns are reported as IntegerField even if they are
really BigIntegerField or BooleanField.
The bug is solved in Oracle 11.2.0.2 and up.
