To me, Tom's feedback felt as being between ambivalent to the change and perhaps
agree with the change, as long as pgindent did not throw a fit, which
it did not.
It definitely did not feel like a -1.

I read your objection to be about the perl code change, whereas the real change
the patch was seeking is in the generated output (lwlocknames.h). I'm guessing
some others may also have taken your feedback to mean the same as I did.

Alvaro committed the following patch, which is better code than mine. If your
objection was about the perl code, perhaps this addresses your concern.

- print $h "#define ${lockname}Lock (&MainLWLockArray[$lockidx].lock)\n";
+ printf $h "#define %-32s (&MainLWLockArray[$lockidx].lock)\n",
+ $lockname . "Lock";

I have ~attached~ linked a comparison of before and after screenshots of the
generated output. It's hard to argue that the generated code in the left/before
image is better than the right/after image.
