What I did:
1. Google "PostgreSQL create database"
2. Click the first link - to PostgreSQL documentation.
3. The command have many options. One of them is "Encoding".
4, Scrolled down for an explanation. The explanation had a link.
5. Clicked the link. Received a page with the list of encodings.
At this point I asked the original question
Does the list on that page stored somewhere? Or it is hardcoded inside
the sources?
That's when I started receiving a references to that table.
Did I ask the wrong question?
And the answer you got was “no, it’s not (i.e., it’s hardcoded inside), but you can get to it indirectly”. In this case if you involve the pgconversion table you should ignore the conversion is default field as it has nothing to do with the question - what encodings does the system recognize. You also got an answer involving generate_series.
