pgstattuple does not work with uppercase table names

Steps to reproduce:

CREATE EXTENSION pgstattuple;

CREATE TABLE "Test" AS SELECT * FROM generate_series(1, 10000);

SELECT * FROM pgstattuple('Test');

ERROR: relation "test" does not exist SQL state: 42P01

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.
