I tried -O0 with same results but I've found something more interesting :

It seems that my compiler version is not 7.4.4m but 7.4.1m, I got lost
in the sgi compiler upgrades. As the folks at nekochan.net provide a binary
package of postgresql for irix that works correctly, I tried compiling
with their build flags but the problem is still there. I asked the
package maintainer which compiler version they use and it's 7.4.4m. So
our problem could very well be a compiler bug.

The mipspro compiler is a proprietary product and I cannot get the
necessary updates so for now I am unable to verify this theory. Anyway,
maybe you should a add a note in the pg irix faq to use the 7.4.4m version
of mipspro when building the sources ?
