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.
