<para>This function takes the table name, the column name and the new
sequence value as parameters. It checks for the existence of the identity column,
and then sets the sequence value (using the sequence_set) and returns the
old sequence value. The table and column names must be properly qualified to
ensure the correct resource is located. The effect of calling this function
is immediate. </para></refsect1>
