So you've got 140 x 45 F5 spanning 4.5m, plus the overhang? I would doubt very much that this pine is adequate, even if you didn't have an overhang. Do you mean the rafter is 4.5m in total length, but at midspan is sitting on top of your 190 x 45 main beam? If this is the case, I would agree with the figures Eastwing said - a bit over a metre
A typical metal roof overhang may be 2 to 4 inches, or even less. Some slight overhang is recommended, in conjunction with a drip edge flashing, to prevent water from getting under the roofing and onto underlying wood. Metal is usually installed on rafters or "strip sheathing" rather than the solid decking used under other materials.
In this project, the pergola was to be set in a corner of the yard, and its rough location was pretty much determined by the existing fences on the adjacent properties and a required 4-foot setback from the property line.
Make the joist into a joist; at this point it is still a beam component. Select, right click, explode, right-click again, and make a component called Pergola Joist. Set the ends to their tentative overhang, 10 inches in this case. Modify the height down to a 2x6 using the scale tool S to push the board down.
Rough-siting the structure is typically basic. Where I build theres a 4-foot setback from the property line to the edge of any structure. Since this pergola is nestled in a corner, my rough layout was pretty much done for me by the existing fences on the adjacent properties.
Each end of the rafter beam will overhang the pergola by 6 inches. Drive a 4-inch-long decking screw at a downward angle through the rafter beam and into one of the horizontal support beams below it. Repeat the procedure with a second screw on the opposite side of the rafter beam, driving the screw into the same horizontal support beam below.

Besides a minimum predicated on the end style, the average set back for the posts is from 12" to 18". I prefer the look of an 18" overhang: it seems just right to me. So for a 16' by 16' overall measurement pergola, the posts will be inset 18" from the corners.
Attaching to your homes Fascia Board. Attaching to the Fascia is a popular installation option, especially for homes that have a low roof overhang height; another reason is for a seamless look where the patio cover is a continuation of the roof. If you have a low roof overhang attaching to the wall just does not allow enough patio cover height
