Psycopg 2.5.2 has been released. You can get it from:
This version contains a few bug fixes over the previous release 2.5.1:
- Fixed segfault pickling the exception raised on connection error (ticket #170).
- Meaningful connection errors report a meaningful message, thanks to Alexey Borzenkov (ticket #173).
- Manually creating lobject with the wrong parameter doesn't segfault (ticket #187).
Thank you very much to all the people who helped during the development!
