Currently schemas are not supported in 5.7. 
I think, that it should be without problems to add optional 'schema' 
to v.database (set GV_SCHEMA) and append schema name to the table name in 

Try to add in grass51/lib/vector/Vlib/field.c at row 276:
if ( G__getenv2 ( "GV_SCHEMA", G_VAR_MAPSET ) )
    sprintf ( buf, "%s.%s", G__getenv2 ( "GV_SCHEMA", G_VAR_MAPSET ), fi->table );
    fi->table = G_store ( buf );
then add in text editor in $GISDBASE/$LOCATION_NAME/$MAPSET/VAR row:
GV_SCHEMA: myschema

let us know if it works, I don't have postgres with schemas.
