If you don’t mind, could you point out the section in the PostgreSql manual/documentation where this is discussed/explained. I have repeatedly read section 8.16.6 (i.e. Composite Type Input and Output Syntax) but it does not appear to include this detail.

Your problem is lower-level than the composite type, it's not understanding csv. Read the copy docs, csv format section to learn more.

https://www.postgresql.org/docs/9.6/static/sql-copy.html

The syntax for the composite is embedded in a csv file so first you have to parse the csv then you pass the result to the composite input constructor. If you enter it literally in a script file you can ignore the csv format stuff and go immediately to the syntax of the Typed data you wish to create.
