One problem of this is that recovery.conf is relative to the configuration
file directory instead of data directory if we treat it as an "include" file.
If your configuration file directory is the same as the data directory, you
don't need to worry about this problem. But if you set data_directory to
the directory other than ConfigDir, the problem might break your tool
which depends on recovery.conf under the data directory.
If we'd like to treat recovery.conf as if it's under the data directory, I'm
afraid that we should add complicated code to parse recovery.conf after
the value of data_directory has been determined from postgresql.conf.
Furthermore, what if recovery.conf has another setting of data_directory?
Since recovery.conf is a configuration file, it's intuitive for me to put it
in configuration file directory rather than data directory. So I'm not inclined
to treat recovery.conf as if it's under data directory. Is this OK?
