Well, why not.

If we add a new file, .gitignore would find about it quickly and
inform about a not-so-clean tree. I would tend to prefer your
approach, here. Relative paths can be useful.

Makes sense to me.
+ log_opts.basedir = getenv("PG_UPGRADE_LOGDIR");
+ if (log_opts.basedir != NULL)
+ log_opts.basedir = strdup(log_opts.basedir);
+ else
+ log_opts.basedir = "pg_upgrade_log.d";
Why is this controlled with an environment variable? It seems to me
that an option switch would be much better, no? While tuning things,
we could choose something simpler for the default, like
"pg_upgrade_log". I don't have a good history in naming new things,
though :)
.gitignore should be updated, I guess? Besides, this patch has no
documentation.
