What's "pg"? It doesn't appear to be e.g. a shell builtin ('type pg'
reports 'bash: type: pg: not found'), and I don't find it in the
archive. For example,
$ apt-file search -x /pg$
finds only two results, from the package grass-core, which appear to be
(parts of? related to?) database drivers.

This doesn't look like a terribly likely scenario to me, but if it *is*
what's happening, that's definitely a bug - though a bug in what is less
than clear.
