Hi, Adrian,

What I noticed is that all encodings are default, as they all have 't'
in the last column.
It's a little confusing...
Not if you read the docs:
https://www.postgresql.org/docs/current/catalog-pg-conversion.html
"The catalog pg_conversion describes encoding conversion functions. See
CREATE CONVERSION for more information."
https://www.postgresql.org/docs/current/sql-createconversion.html
"Conversions that are marked DEFAULT can be used for automatic encoding
conversion between client and server. To support that usage, two
conversions, from encoding A to B and from encoding B to A, must be
defined."
From the https://www.postgresql.org/docs/current/catalog-pg-conversion.html:
[quote]
condefault bool
True if this is the default conversion
[/quote]
So, what info do I trust?
Both.
In your setup all the installed encoding conversion functions are also
the default for those conversions. It is possible to create/install a
conversion function that is not the default.
Thank you.
