not now about current version of arcGIS, but till version 9.2 there were 
no support for open-source solutions like postgreeSQL and postGIS. Only 
proprietary back-ends like Oracle Spatial etc. But as I know from 
version 9.3 there is extension "data Interoperability" (looks like 
warper for GDAL/OGR) so with this solution you can have access to postgis.

The second solution: Oracle Spatial as backend for Arc and link via OGR 
to GRASS, but it is only theoretical idea I did not test it.
