Comments and changes to this ticket
I've tried installing clang on ubuntu and compiling psycopg and found no problem (I was signaled a warning unrelated to what you have reported here, and I'm working on fixing that).
It must be something related to your platform, not strictly to clang. As it is now we cannot debug it. Either you will have to fix yourself or provide us an ssh access to a box to test it.

Psycopg is the most used PostgreSQL adapter for the Python programming language. At the core it fully implements the Python DB API 2.0 specifications. Several extensions allow access to many of the features offered by PostgreSQL.
