36.45. sql_languages
  The table
  
   sql_languages
  
  contains one row for
   each SQL language binding that is supported by
  
   PostgreSQL
  
  .
  
   PostgreSQL
  
  supports direct SQL and
   embedded SQL in C; that is all you will learn from this table.
 
This table was removed from the SQL standard in SQL:2008, so there are no entries referring to standards later than SQL:2003.
