You might have the same problem which was reported before. http://archives.postgresql.org/pgsql-hackers/2011-06/msg00661.php That problem was fixed, and the fix will be included in next minor update (i.e., 9.0.5). http://archives.postgresql.org/pgsql-committers/2011-06/msg00101.php Of course, you can avoid the problem by building PostgreSQL with gcc != 4.6.0, I think.
