Yes, you can change it at compile time. It's the NAMEDATALEN
definition. Don't expect the resulting data directory to be compatible
with vanilla sources though -- you will only be able to use that with
patches sources. Of course, if you produce dump files with long names,
they will be truncated if exported into nonpatched systems too, so take
caution.
