Looks good to me.
Although I have to admit I am wondering whether there still is a point
in using pg_malloc() et al. instead of just using palloc() et al. There
doesn't seem to be too much gained by that. But thats probably better
done as another patch ontop of this if at all.

If anything it should be plain write()s, as that wouldn't allocate
memory... But otherwise I aggree.
