During an exp-run for llvm 15 (see bug 265425), it turned out that
databases/soci failed to build with clang 15:

This is because soci declares its RandomNumberGenerator class with a
result_type of std::ptrdiff_t, which is signed. However, the urng class used
for std::shuffle must have an unsigned integer type as its result type. Use
std::size_t instead.
