Thanks for doing the legwork. Line 335 of fd.c is
return posix_fadvise(fd, offset, amount, POSIX_FADV_DONTNEED);
which means you've got one of those nasty Linux versions that claims to
have posix_fadvise but it dumps core when executed. As a workaround
you can comment out "#define USE_POSIX_FADVISE" in
src/include/pg_config_manual.h before building.
What kernel and glibc versions are you running, exactly?
regards, tom lane
