Write a function that updates version_actual_period_start with type timestamp. Look for an entry with the condition version_actual_period_end > current_timestamp . the user specifies the desired date, and the previous one, according to the time of the relevance of the record, is updated version_actual_period_end-becomes the same, but 1 second less. Input parameters time, database table name, version_meta_id array. Plpgsql

CREATE OR REPLACE FUNCTION update_version_actual_period_start(
  time timestamp,
  table_name varchar(255),
  version_meta_id int
) RETURNS void AS
$$
    BEGIN
        EXECUTE format(
            '
            UPDATE %I
            SET version_actual_period_end = time - interval ''1 seconds''
            WHERE time > current_timestamp
            AND version_actual_period_end > current_timestamp
            AND version_meta_id = %L ',
            table_name,
            version_meta_id
        );
    END;
$$ LANGUAGE plpgsql;
