Comment(by pracine):

 The problem seems to come from "get_rt_context" which switch the context
 of the most PostGIS raster functions preventing the PostgreSQL function
 manager to free the memory allocated to the context.

 Shall we not delete this context using rt_context_destroy(ctx) in all the
 functions except those returning PG_RETURN_POINTER(pgraster)?
