Tom Lane 3f244d020f Make new GENERATED-expressions code more bulletproof. 
In commit 8bf6ec3ba I assumed that no code path could reach
ExecGetExtraUpdatedCols without having gone through
ExecInitStoredGenerated.  That turns out not to be the case in
logical replication: if there's an ON UPDATE trigger on the target
table, trigger.c will call this code before anybody has set up its
generated columns.  Having seen that, I don't have a lot of faith in
there not being other such paths.  ExecGetExtraUpdatedCols can call
ExecInitStoredGenerated for itself, as long as we are willing to
assume that it is only called in CMD_UPDATE operations, which on
the whole seems like a safer leap of faith.

Per report from Vitaly Davydov.

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.
Also, to use "make installcheck", you must have built and installed
contrib/hstore in addition to the core code.

Run
    make check
or
    make installcheck
You can use "make installcheck" if you previously did "make install".
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.

See src/test/perl/README for more info about running these tests.
