Pushed, thanks everyone!

On eelpout two test_decoding tests failed:

test ddl                          ... FAILED
test rewrite                      ... FAILED

The output has several cases where pg_logical_slot_get_changes() is
invoked and then fails like this:

   SELECT data FROM pg_logical_slot_get_changes('regression_slot',
NULL, NULL, 'include-xids', '0', 'skip-empty-xacts', '1');
! ERROR:  incorrect resource manager data checksum in record at 0/1BD6600

Not sure why it would break when called by pg_logical_slot_get_changes()...

Yep. I got the code before the main loop, to handle the first 1-7 unaligned bytes, wrong. Apparently those are the only tests that call the CRC function with very short and unaligned input.

I've got a fix ready, and I'm running "make check-world" on my ARM box now, to make sure there aren't any more failures. I'll push the fix once that's finished. Should've run the full test suite before pushing in the first place..
