3/3 Now I can finally write the chapter on Java and JDBC with a little JavaFX thrown in for good luck or good confusion.

2/3 What drove me the craziest was that 'USE DATABASE' must be used as a single command in psql and not in the sql script. Going the other way I assume Postgres users moving to MySQL might also be confused? Actually, no. The commands they must use only in 'psql' can be used in the MySQL equivalent 'mysql.exe' as well as the script. I have also figured out that the commands that are barred from a script in Postgres is a result of heightened security as compared to MySQL, or so I assume.
1/3 It has taken me a week to figure out how to use Postgres on Windows although the issues I had would appear on any OS that Postgres supports. My problem stemmed from the fact that as a long time MySQL user I was thrown by the fact that a small number of DDL commands cannot be run from a script such as 'CREATE DATABASE' but rather through it's command line interface program 'psql'. MySQL, on the other hand, allows all DDL commands in a script.
How do you know that there is nothing on TV or Streaming? When you have been watching the splashdown and recovery of the Artemis II capsule since 6:45. It’s 9:38 now. Astronauts just emerging.

Every time I have had an AI create a representation of me it always gives me a full head of hair. The only good thing about AI, so far.
After more than 4 days trying to figure out the best way to explain logging I have come to the conclusion that for those just starting out with Java the only reasonable choice is the logger in Java, java.util.logging.
Logback, Log4j2, and the interfaces System.Logger and SLF4J just muddy the waters. I know that in using a facade/interface I can easily change implementations. Does this ever happen in the wild? Differences in the Levels is another pain in the ass. Time for KISS.
