Yes, before updating you definitely want to do that, but it usually
takes me a few tries to undo parts where I've gone wrong. So diffs
regularly happen along the way.

Anyway, don't maintain by hand

The below should make .cvsignore entries for most files. I can test it,
and clean it up to be put under src/tools if wanted if this method is
ok. No, it's not perfect but running it shortly before or after a
pgindent run would cover 90% of the cases.

#!/bin/sh
# Run from PGSQL directory
./configure
find * -name .cvsignore -delete
make all check
cd doc/src && make all && cd ..
cvs diff 2>&1 | perl -e '
while ($line = <STDIN>)
{
chomp($line);
if ($line =~ /^\?\s.*\/.*/)
{
$line =~ s/^\?\s(.*\/)([^\/]+)$/echo \"$2\" >> $1.cvsignore\n/;
print $line;
} elsif ($line =~ /^\?\s/)
{
$line =~ s/^\?\s([^\/]+)$/echo \"$1\" >> .cvsignore\n/;
print $line;
}
}' | sh
