The .load command attempts to load and link an
SQLite dynamic extension. If no entry point is given, the
default sqlite3_extension_init name will be
used.
Extensions that redefine existing SQL
functions (including built-in functions) must be loaded using
this command. Using the SQL function load_extension() will not work, as an extension
cannot redefine an existing function while an SQL statement is
being processed (for example, the statement executing the SQL
function load_extension()).
