As 1.9 is not final yet we can't definitely answer that. (We might still need a
format bump, etc. ... although we will try to avoid that)
Currently it looks like you don't need to call svn upgrade.
And it looks like both 1.9 and a future 1.8 will improve performance on working
copies initially created/upgraded with 1.8.0-1.8.7, but not already explicit
'svn upgrade'-d with a later version, when it internally uses Sqlite 3.8 or
later.
The performance fix is nominated for both 1.9 and 1.8. For 1.9 it is accepted
for backport, but for 1.8 it misses a final vote.
