Interesting thought....

At $work:
postgresql95-server.x86_64               9.5.10-1PGDG.rhel7              @pgdg95

postgres=> select 0.5678 operator(pg_catalog.^) (-85);
ERROR:  division by zero
postgres=> select 0.5678::numeric operator(pg_catalog.^) (-85::numeric);
ERROR:  division by zero

Also at home in a gentoo 9.5.1 ebuild...
Also in a build from e35dba475a440f73dccf9ed1fd61e3abc6ee61db in git.

All x86_64 ....
