Steps to reproduce:

You need to quote the identifier:
SELECT * FROM pgstattuple('"Test"');
 
Note the double quotes inside the string, so "singlequote-doublequote-Test-doublequote-singlequote".

Thanks,

 

Could it be helpful to explain this in the user manual?

(please avoid top-posting)

It's documented at https://www.postgresql.org/docs/11/static/sql-syntax-lexical.html#SQL-SYNTAX-IDENTIFIERS, as it's a pretty fundamental part of SQL. We definitely could move it to a more prominent place, but it would make little sense to document it individually for every place that uses one I think.
