Comment(by strk):

 So finally I pushed everything as r12941 in trunk.
 We have:

  - ST_Retile returns SETOF raster
  - ST_CreateOverview returns REGCLASS

 The former is more flexible and doesn't write to the db.
 The latter is more easy-to-use and goes on to create the tables and add
 the constraints.
