+From C<debian/control.in>, look for the package name containing the
+B<PGVERSION> placeholder, and return it in the format suitable for passing to
+B<pg_buildext>, i.e. with B<PGVERSION> replaced by B<%v>.
+
+For B<Package: postgresql-PGVERSION-unit> it will return B<postgresql-%v-unit>.
+
+Errors out if more than one package with the B<PGVERSION> placeholder is found.
