title: Oracle built-in functions metadata
body: <p>Is there a way to get metadata for the Oracle built-in aggeregate and other functions such as <code>AVG, STDDEV, SQRT,</code> etc.?
  I need to know object id and arguments meta.</p>
  
  <p>In the <code>SYS.ALL_OBJECTS</code> view I couldn't find anything useful. I also tried to search in <code>SYS.ALL_ARGUMENTS</code> view by object_name.</p>
  
  <p>Is there views or tables with built-in functions with data similar to <code>SYS.ALL_OBJECTS</code> and <code>SYS.ALL_ARGUMENTS</code>?</p>
