You didn't build git head under --enable-cassert, did you?

Any chance you can do a oprofile or gprof of head's pg_dump dumping
out of head's server? That really should be a lot faster (since
commit eeb6f37d89fc60c6449ca12ef9e) than dumping out of 9.2 server.
If it is not for you, I don't see how to figure it out without a
profile of the slow system.

Cheers,

Jeff
