I didn't look at the code more than necessary to make the build work.

As far as functionality goes, it does exactly what I needed it to do;
the output is very clear. I wanted to see how much WAL is being
generated from SELECT FOR UPDATE locks.

Here are some thoughts:

The "FPI" acronym made me wonder at first. Perhaps "Full page image
size" would be clearer (exactly 20 characters long, so it fits).

But on the other hand, I find that the table is too wide, I always
need to stretch my terminal window to fit it. I don't think we need to
accommodate for 10^20 bytes ~ 87 exabytes of WAL files. :)

You might also add units (kB/MB) to the table like pg_size_pretty,
although that would make the magnitudes harder to gauge.

Oh right you are, I don't know how that happened. I also missed some
record types (Btree/0x80, Btree/0xb0).
