I grabbed the patched BSD indent from a mirror. Here's a couple of points:

. with a little trial and error GNU indent 2.2.9 actually did quite a 
reasonable job for me last night. But I guess YMMV. I'm curious to know 
what nasty mangling it does.
. the file is a compressed tar file - it would be better to have a file 
extension of .tgz or .tar.gz  instead of just .gz, so that this is apparent.
. I had to hack the makefile for my linux box for a reasonably clean 
build, so that the CFLAGS on the install line doesn't override setting 
the defines, and the compiler won't complain about isblank and/or strdup 
and/or fileno. The diff is attached for anyone interested.

GNU indent does a reasonable job, but it did some strange spacing for
function definitions, if I remember correctly.  Can you test by running
pgindent and gnuindent through the /executor files and do a diff to see
the differences in formatting?

Done.  Sorry.

OK, I updated it on the ftp site.  Can you download it?  It should have
size 41192.  Is _GNU_SOURCE required?  I didn't add that, but fixed the
install part.

after I added -ncdb to the GNU indent options in pgindent, the main 
effect appears to be that it joins function calls across lines, 
sometimes in weird ways. I guess that's bad enough for us not to use it 
unless someone knows a way to turn that off.

Example (second case is bsd indented):

***************
*** 217,223 ****
  execTuplesHashPrepare(TupleDesc tupdesc,
                      int numCols,
                      AttrNumber *matchColIdx,
!                     FmgrInfo **eqfunctions, FmgrInfo **hashfunctions)
  {
    int         i;
 
--- 234,241 ----
  execTuplesHashPrepare(TupleDesc tupdesc,
                      int numCols,
                      AttrNumber *matchColIdx,
!                     FmgrInfo **eqfunctions,
!                     FmgrInfo **hashfunctions)
  {
    int         i;

I am being refused connection to developer.postgresql.org and it hasn't 
reached the mirrors yet AFAICS.

Yes, this is exactly what I remember, and I can think of no way to
"script" that fix.

Let me know when you can download.  I sure it will hit the mirrors
shortly.

The fact that we have a way to auto-indent 450k lines of C code with
few/no complaints is amazing in itself.

Re: bsd indent

BTW, there's a bug in entab.c, too. This line:

#include "../include/c.h"

should read

#include "../../include/c.h"
