Sorry for the non-answer via mail so far.

As said on IRC, everything else works. We are building lots of server-
side extensions for various PG versions in parallel, all using the
9.3 libpq5 and libpq-dev.

There are/were some knows problems where the client headers depend on the
server, though that should be a different issue.

I haven't had time to look into pg_repack yet. Possibly I can come up
with a solution once these minor releases are out of the door.

Ack.

Right, plus postgresql-server-dev-<version>.
