So how did you install Postgres(and from where) and was it different for
9.4 versus 9.5?

Hmm, pg_upgrade_support isn't a separate library anymore; it's been merged
into core.  I would not have expected that to cause any problems, because
the functions in that library shouldn't have been referenced in your old
database in the first place.  They were supposed to be installed and then
removed again during the process of (prior versions of) pg_upgrade.

I'm guessing you had leftovers from old failed pg_upgrade attempts that
you never completed.

What you want to do is simply manually drop the functions referencing
$libdir/pg_upgrade_support.  A look into the pg_upgrade sources suggests
that this ought to do it:

DROP SCHEMA IF EXISTS binary_upgrade CASCADE;

though you'll probably have to do that in every database of the
installation.

            regards, tom lane

Hello,

I tried to delete all binary_upgrade schematas using this:

$ psql -tc "SELECT datname FROM pg_database" -U postgres -p 5433 | xargs -I
{} psql -d {} -U postgres -p 5433 -tc "drop schema if exists binary_upgrade
cascade;"

But got this:
output is not a tty

So I got the dblist from pgadmin and saved to file:
That worked:
$ cat dblist.txt | xargs -I {} psql -d {} -U postgres -p 5433 -tc "drop
schema if exists binary_upgrade cascade;"

pg_upgrade succeeded with the step:
Checking for presence of required libraries                 ok

But then I got:
Checking database user is the install user
Only the install user can be defined in the new cluster.
Failure, exiting

But this is the next story ;-) I can assure that deleting the schematas from
the source db solves my initial problem.

Thanks for your help,
Tobias Schönit
