This is like CVE-2018-1058 commit 582edc369cdbd348d68441fc50fa26a84afd0c1a. Today, a malicious user of a publisher or subscriber database can invoke arbitrary SQL functions under an identity running replication, often a superuser. This fix may cause "does not exist" or "no schema has been selected to create in" errors in a replication process. After upgrading, consider watching server logs for these errors. Objects accruing schema qualification in the wake of the earlier commit are unlikely to need further correction. Back-patch to v10, which introduced logical replication. Security: CVE-2020-14349

Regression tests for subscription/logical replication
=====================================================
This directory contains a test suite for subscription/logical replication.
Running the tests
=================
NOTE: You must have given the --enable-tap-tests argument to configure.
Run
make check
or
make installcheck
You can use "make installcheck" if you previously did "make install"
(including installing the hstore extension). In that case, the code
in the installation tree is tested. With "make check", a temporary
installation tree is built from the current sources and then tested.
Either way, this test initializes, starts, and stops several test Postgres
clusters.
