PostgreSQL version: 11.5
Operating system: Ubuntu 18.04
Description:
# psql --version
/usr/lib/postgresql/11/bin/psql: symbol lookup error:
/usr/lib/postgresql/11/bin/psql: undefined symbol: PQsslInUse
The cluster itself seems fine, pgcli can connect to it for instance.
On an Ubuntu 16.04 machine, psql 11.5-1.pgdg16.04+1 works fine.
