A GRASS "database" isn't a PostgreSQL database; it's just a directory
tree. While a few GRASS programs (i.e. the ones which end in ".pg")
can use a PostgreSQL database, this isn't the case for most of the
modules.

The format of GRASS files doesn't depend upon the OS, or even the CPU,
so there isn't any need to "export" the data.
