COPY statement: no list of the allowed values for "format_name"

Description:

Look at the account of the COPY statement, here:

https://www.postgresql.org/docs/11/sql-copy.html

and see this:

«
[ [ WITH ] ( option [, ...] ) ]
»

It goes on to say this:

«
where option can be one of:

FORMAT format_name
»

But there's no list of the allowed values for "format_name". The same holds
for other options like, for example, "encoding_name".

I tried to provoke the list by using "with (format 'dog')". I got the 22023
error:

«
COPY format "dog" not recognized
»

But there was no list of the allowed values.
