Thank you for the report. I had already refactored mogrify to use more code in common with execute (mostly to support unicode queries) and as a result this bug was fixed. I will add a regression test though.
In : cursor.mogrify('select %s', (Decimal('3.27'),))
Out: 'select 3.27'
Code available in the python2 branch of my git repository http://tinyurl.com/piro-psycopg2 <git://src.develer.com/users/piro/psycopg2.git>, soon to be released.
I've found the cause of the crash: the Decimal adapter incorrectly assumed the existence of the
is_finite()method: it was actually introduced somewhere after 2.5.1 and is available e.g. in 2.5.4.
I've fixed the issue in my repos, but the bug is still present in the 2.3.0-beta1. Jason is preparing a Window package.
