RE: Patch for migration of the pg_commit_ts directory

Hi,

Thanks for updating the patch.

```
+my ($xid,$ts) = $resold =~ /\s*(\d+)\s*\|(.*)/;
```

Per my understanding $ts is not used here. Can you remove it?

Apart from above, I found some cosmetic issues. Please see attached
my fix which can be applied atop HEAD. Can you check and include if
it is OK?

Best regards,
