Segfault in 7.4.1 (and 7.3.4) during vacuum analyze

Greeting,

This is mainly just a heads up, I'm going to be recompiling with
symbols and rerunning the test after I get to work, but I'm getting a
segfault consistantly when doing a vacuum analyze. The trace is from
7.4.1 but I upgraded to 7.4.1 because the same was happening under
7.3.4. Both installed from Debian/sid and the system is now
up-to-date with Debian/sid. Here's the trace:

Program received signal SIGSEGV, Segmentation fault.
