My suggestion is to not use PostGIS for big rasters, unless you have to,
because you want to use the data in a specific application for example.
Note r.external and r.external.out of GRASS GIS 7 for avoiding data duplication:
https://grass.osgeo.org/grass70/manuals/r.external.html
https://grass.osgeo.org/grass70/manuals/r.external.out.html
Note also that in PostGIS you can "store" raster data outside the
database and only register a reference to the file and the necessary
metadata in the database (cf the -R flag of raster2pgsql) [1].
That way you can access the same data from GRASS GIS and from PostGIS,
avoiding imports and exports.
