I just did a fresh install of PG 10.6 on Linux Mint 19.1 Tessa, using
the version in the repos:

postgres=# select version();
PostgreSQL 10.6 (Ubuntu 10.6-0ubuntu0.18.04.1) on x86_64-pc-linux-gnu,
compiled by gcc (Ubuntu 7.3.0-16ubuntu3) 7.3.0, 64-bit
(1 row)

I didn't have to do anything with LD_LIBRARY_PATH because I did a
default installation. Function PQsetErrorContextVisibility is found


If I do "ldd /usr/lib/postgresql/10/bin/psql" the second entry I see is
this: => /usr/lib/x86_64-linux-gnu/ (0x00007f93b7f20000)

So, find where* is installed on your system, and make sure
that is on your LD_LIBRARY_PATH. Use ldd to ensure that psql is fully
linked to required libraries.
