title: ERROR: relation "table" does not exist, even though both the database and the table exist
body: <p>I'm using cockroachdb, which is essentially a superset of postgres and I can't understand why the statement:</p>
  <pre><code>select * from _a66df261120b6c23.tabDefaultValue;
  </code></pre>
  <p>results sin the error:</p>
  <pre><code>ERROR: relation &quot;_a66df261120b6c23.tabdefaultvalue&quot; does not exist
  </code></pre>
  <p><code>show databases</code> gives me:</p>
  <pre><code>    database_name   | owner | primary_region | regions | survival_goal
  --------------------+-------+----------------+---------+----------------
    _a66df261120b6c23 | root  | NULL           | {}      | NULL
    defaultdb         | root  | NULL           | {}      | NULL
    postgres          | root  | NULL           | {}      | NULL
    root              | root  | NULL           | {}      | NULL
    sammy             | root  | NULL           | {}      | NULL
    system            | node  | NULL           | {}      | NULL
    test123           | root  | NULL           | {}      | NULL
    test3             | root  | NULL           | {}      | NULL
    test4             | root  | NULL           | {}      | NULL

    test9             | root  | NULL           | {}      | NULL
  </code></pre>
  <p>and <code>show tables from _a66df261120b6c23</code> gives me:</p>
  <pre><code>  schema_name |    table_name     | type  | owner | estimated_row_count | locality
  --------------+-------------------+-------+-------+---------------------+-----------
    public      | __Auth            | table | root  |                   0 | NULL
    public      | tabDefaultValue   | table | root  |                   0 | NULL
  
  </code></pre>
  <p>The database and the table both exist, so why does <code>select * from _a66df261120b6c23.tabDefaultValue;</code> fail? Strange thing is when I run <code>\dt</code> all I get is:</p>
  <pre><code>  schema_name | table_name | type  | owner | estimated_row_count | locality
  --------------+------------+-------+-------+---------------------+-----------
    public      | sammy      | table | root  |                   0 | NULL
  </code></pre>
  <p>How do I actually get the <code>select</code> statement to work? Thank you</p>
