Thanks, and thanks for catching be_gssapi_write(), which I had missed
due to not having gssapi enabled in my test build.

I had a more thorough read-through this time (as well as applying and
building it), and it does make the code a lot more readable.
I noticed you in some places added extra parens around remaining casts
with offset additions, e.g.
- XLogRegisterData((char *) old_key_tuple->t_data +
SizeofHeapTupleHeader,
+ XLogRegisterData(((char *) old_key_tuple->t_data) +
SizeofHeapTupleHeader,
old_key_tuple->t_len -
SizeofHeapTupleHeader);
But not in others:
- memcpy((char *) tuple->t_data + SizeofHeapTupleHeader,
- (char *) data,
- datalen);
+ memcpy((char *) tuple->t_data + SizeofHeapTupleHeader, data,
datalen);
I don't have a particularly strong opinion either way (maybe -0.2 on the
extra parens), but I mainly think we should keep it consistent, and not
change it gratuitously.
Greppig indicates to me that the paren-less version is more common:
$ git grep -P '\(\w+\s*\**\) [\w>-]+ \+ \w+' | wc -l
283
$ git grep -P '\(\(\w+\s*\**\) [\w>-]+\) \+ \w+' | wc -l
96
So I think we should leave them as they are.
