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 public.update_version_actual_period_start(
    IN p_time timestamp,
    IN p_table_name character varying,
    IN p_version_meta_id integer[])
  RETURNS integer AS
$BODY$
declare 
    l_count integer;
    l_version_actual_period_start timestamp;
    l_version_actual_period_end timestamp;
BEGIN
    l_count = 0;
    FOR i IN 1..array_length(p_version_meta_id, 1) LOOP
        SELECT version_actual_period_start, version_actual_period_end
        INTO l_version_actual_period_start, l_version_actual_period_end
        FROM $1
        WHERE version_meta_id = p_version_meta_id[i];
        IF (l_version_actual_period_end > current_timestamp) THEN
            l_count = l_count + 1;
            l_version_actual_period_start = p_time;
