I ended up splitting this up differently.  I applied to part of the
second patch that works around the length issue in tablespaces.  So the
tests now pass in 9.4 and up even in working directories with long
names.  This clears up the regression in 9.4.

The remaining, not applied patch is attached.  It errors when the file
name is too long and adds tests for that.  This could be applied to 9.5
and backpatched, if we so choose.  It might become obsolete if
https://commitfest.postgresql.org/action/patch_view?id=1512 is accepted.
 If that patch doesn't get accepted, I might add my patch to a future
commit fest.
