Does CREATE DATABASE *convert text*?  (I think you might be
misunderstanding the purpose of the pg_conversion table.)

Wouldn't it only *convert* text when a client is inserting text of encoding
X into a table with encoding Y?

ISTM that pg_conversion says whether PG knows how to convert from X to Y,
not the encoding scheme you defined when creating the db.
