Yeah.  Also note that 8.3 to 9.6-or-newer is going to be a pretty
huge jump in terms of minor compatibility issues (have you read
all the relevant release notes?).  So there's something to be said
for breaking this down into two steps: update to 9.4, test/fix
your applications against that, then make a second jump to something
current.  Each of those jumps could be handled by the respective
version of pg_upgrade.  I concur with Laurenz's advice that stopping
at 9.6 is probably not your best choice for a migration today.
