Why not use pg_ls_dir()? An FDW would be mighty awkward to use for this purpose, even if one existed.
It cannot be used for an arbitrary directory:
" Only files within the database cluster directory and the log_directory can be accessed. "
Personally, I don't know what use such a function would be. It would be executed on the _SERVER_, not the client. And that is probably why the pg_ls_dir() is restricted. If it weren't it could be a security (or privacy) violation.
