Write equivalent queries for all databases as these two for MySQL and PostgreSQL :

MySQL :
select  current_date() as cur_date,
        current_time() as cur_time,
        current_timestamp() as cur_timestamp,
        utc_date() as cur_utc_date,
        utc_time() as cur_utc_time,
        utc_timestamp() as cur_utc_timestamp
go
select  cast(current_date() as char) as cur_date,
        cast(current_time() as char) as cur_time,
        cast(current_timestamp() as char) as cur_timestamp,
        cast(utc_date() as char) as cur_utc_date,
        cast(utc_time() as char) as cur_utc_time,
        cast(utc_timestamp() as char) as cur_utc_timestamp
 

PostgreSQL :
select  current_date as cur_date,
        current_time as cur_time,
        current_timestamp as cur_timestamp,
        current_date at time zone 'UTC' as cur_utc_date,
        current_time at time zone 'UTC' as cur_utc_time,
        current_timestamp at time zone 'UTC' as cur_utc_timestamp
go
select  to_char(current_date, 'MM-DD-YYYY') as cur_date,
        //to_char(current_time, 'HH24:MI:SS') as cur_time,
        to_char(current_timestamp, 'MM-DD-YYYY HH24:MI:SS TZ') as cur_timestamp,
        to_char(current_date at time zone 'UTC', 'MM-DD-YYYY') as cur_utc_date,
        //to_char(current_time at time zone 'UTC', 'HH24:MI:SS') as cur_utc_time,
        to_char(current_timestamp at time zone 'UTC', 'MM-DD-YYYY HH24:MI:SS') as cur_utc_timestamp
