Hello.  We identified the same problem.  Sam Gwydir and Josh Clulow were able to put together the appropriate fix after.

The breakage in src/backend/port/sysv_shmem.c and src/include/storage/dsm_impl.h should be back ported to all supported versions (the regression was introduced between the 9.2 and 9.3 branches).

Personally I don't think "breakage" is quite the right work.

I also don't like that we're unconditionally not using
USE_ANONYMOUS_SHMEM - doesn't that run into similar config limits on
solaris based stuff as it does on linux etc?

I think if we want to do this, we should rather go with a patch like
