i.e. and e.g.

I happened to see the message below.

> WARNING:  new data directory should not be inside the old data directory, e.g. %s

The corresponding code is

> ... the old data directory, e.g. %s", old_cluster_pgdata);

So, "e.g." (for example) in the message sounds like "that is", which I
think is "i.e.".  It should be fixed if this is correct.  I'm not sure
whether to keep using Latin-origin acronyms like this, but in the
attached I used "i.e.".

regards.
