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.
