Thank You for the patch. In one of my tests, I noticed that I got
negative checksum:

postgres=# SELECT * FROM pg_get_logical_snapshot_meta('0/3481F20');
   magic    |  checksum  | version
------------+------------+---------
 1369563137 | -266346460 |       6

But pg_crc32c is uint32. Is it because we are getting it as
Int32GetDatum(ondisk.checksum) in pg_get_logical_snapshot_meta()?
Instead should it be UInt32GetDatum?

Same goes for below:
values[i++] = Int32GetDatum(ondisk.magic);
values[i++] = Int32GetDatum(ondisk.magic);

We need to recheck the rest of the fields in the info() function as well.

thanks
Shveta
