Does it also happen when you open a psql session and do?:
psql>select * from ext_table limit 1;
No messages are printed whilst the session is open. However, when I
quit the session by typing “\q” /after/ entering the command above, the
LOG message appears. It does not appear when I query tables from my_db
exclusively, though, i.e. when I do not access the Foreign Table.
Seems to back up Tom Lanes's observation:

"If these are about the FDW connections, maybe the answer is that
postgres_fdw ought to establish a backend-exit callback in which
it can shut down its connections gracefully. If it's doing that
now, I sure don't see where."
Looks like it might be time to file a bug report:
https://www.postgresql.org/account/submitbug/
I am not seeing --contrib which is where I would expect postgres_fdw
to come from.
Apparently, it is packaged with the main server deb file:
albrecht@odysseus:~$ dpkg -S $(find /usr/share/postgresql -name "*fdw*")
postgresql-10: /usr/share/postgresql/10/extension/file_fdw--1.0.sql
postgresql-10: /usr/share/postgresql/10/extension/file_fdw.control
postgresql-10: /usr/share/postgresql/10/extension/postgres_fdw--1.0.sql
postgresql-10: /usr/share/postgresql/10/extension/postgres_fdw.control
…and additionally it contains /usr/lib/postgresql/10/postgres_fdw.so, of
course. I double-checked the package
http://apt.postgresql.org/pub/repos/apt/pool/main/p/postgresql-10/postgresql-10_10.3-1.pgdg90+1_amd64.deb;
it is installed properly.
My mistake, I was looking at an install that had Postgres 9.6. In that
case the files for 9.6 where in --contrib, presumably because 10 is now
the default.
Is --contrib installed?
No. But the deb file postgresql-contrib_10+190.pgdg90+1_all.deb
contains only the changelog and copyright files.
If not where is postgres_fdw coming from?
See above…
Cheers,
Albrecht.
