Sadly Windows is still in the dock. The jury is still out.
Turns out the "without a hitch" was based on cached wheels.
I'm going to start from scratch with new projects using Pythons 3.8,
3.10 and 3.11 and report back.
Report summary:
pip install works well with Python 3.8 and 3.10 (and presumably 3.9) but
3.11 fails.
Report conclusion:
As indicated in this thread, pip cannot find Python 3.11 wheels and
therefore needs to compile from source. It is looking for Microsoft's
C++ compiler version 14.
I'll (gulp) attempt to swallow the Koolaid.
See error below ...
Cheers

DEPRECATION: psycopg2 is being installed using the legacy 'setup.py
install' method, because it does not have a 'pyproject.toml' and the 'wheel'
package is not installed. pip 23.1 will enforce this behaviour change. A
possible replacement is to enable the '--use-pep517' option. Discussion can be
found athttps://github.com/pypa/pip/issues/8559
