[Gmsh] Avoid Mesh refinement at coast

I'm trying to mesh a basin for my Finite Element ocean model.
I'm forcing the mesh by means of a postview file, that has
almost all constant values apart from some areas where I need
refinement because of bathymetry.
I've seen that, even where the postview is constant, the 2D
mesh that I get is refined in correspondence of coast boundaries,
and this is what I do NOT want. It is like postview is ignored at coast.
I've seen that the behaviour is different between physical lines and
normal lines. At physical boundaries the grid that I get is evenly spaced,
like I expect.
Is there a way to make gmsh treat all boundaries like physical?
I've tried several options for the element size but in vain, I alway get
a refinement at coastlines even though the postview is constant.
P.S. I'm using 2.13.2 version
