What it looks like to me is something is miscomputing a memory request
size and asking for some silly amount of memory. I think you're dealing
with a software bug, not inadequate configuration.

The first theory that comes to mind is that powa_take_snapshot() requires
some updates for PG10. I do not know what that function is or where you
got it from, but if there's any C code involved, you need to discuss this
with its developer(s).
