DELETE FROM migrations WHERE "name" = 'DeleteCreatedAt1697420555911';

When I tried this code, the createdAt value wrongly converted. So I wrote a new function for me.

If anyone facing same issue with me, try this function.

CREATE OR REPLACE FUNCTION base36_decode(value TEXT)
RETURNS BIGINT AS $$
DECLARE
    result BIGINT := 0;
    digit INT;
    len INT;
    i INT;
    char CHAR;
    base INT := 36;
BEGIN
    -- Length of the input string
    len := LENGTH(value);

    -- Iterate through each character in the string
    FOR i IN 1..len LOOP
        char := SUBSTRING(value FROM i FOR 1);

        -- Determine the numeric value of the character
        IF char ~ '[0-9]' THEN
            digit := CAST(char AS INT);
        ELSIF char ~ '[A-Z]' THEN
            digit := ASCII(char) - ASCII('A') + 10;
        ELSIF char ~ '[a-z]' THEN
            digit := ASCII(char) - ASCII('a') + 10;
        ELSE
