At the moment, running pg_migrate requires a valid GHC installation, because migration scripts are run directly using runghc. Instead, it would be useful to provide a "compilation" mode to build a single "migrater" executable that can be used in the absence of a Haskell installation. This mode would collect the migration scripts, editing them as necessary to make them into Haskell modules that could be compiled along with a suitable main program to make a standalone migration runner.
