-----------------------------------+----------------------------------------
HaskellDB generates code with large types for database tables. This code
 must be compiled with the -fcontext-stack flag, with an argument that
 depends on the number of columns in the table. Since -fcontext-stack is a
 static flag at the moment, the user who wants to use a generated module
 has to look in the generated cod for a comment that says to use for
 example -fcontext-stack64. If -fcontext-stack could be set in a pragma the
 user would be spared this problem.

 In general, since the -fcontext-stack flag needed depends on the code, it
 would seem reasonable to be able to set it in the code.
