Attached is version 4, which excludes the output file from pgindent,
to match recent commit 74d4608f5. Since it won't be indented again, I
also tweaked the generator script to match pgindent for the typedef,
since we don't want to lose what pgindent has fixed already. This last
part isn't new to v4, but I thought I'd highlight it anyway.
