Yes, the database is supposed to be able to run without SSE2, as long as
it is built with gcc and not clang, and without any architecture flags
that imply SSE2 support.
I'm pretty sure nothing in our buildfarm is i386 without SSE2 though.

Your backtrace implies that you are running with checksums enabled;
true?
You should be able to build the port with debugging enabled by setting
WITH_DEBUG=1 in the environment or on the make command line. (I have not
yet tried this myself - I rarely build from the port.)

What is the exact query?
I'm doing some investigations of my own, I may have more questions
later.
