Answer 1

the month must be written like this 'Sep' or 'September' and then you can use

this for Sep:

select to_timestamp('6-Sep-2022 18:21:33','dd-Mon-yyyy HH24:MI:ss')::timestamp

this for September:

select to_timestamp('6-September-2022 18:21:33','dd-Month-yyyy HH24:MI:ss')::timestamp

documentation here

you can convert 'Sept' in 'Sep' with:

select to_timestamp( replace( '6-Sept-2022 18:21:33','Sept','September'),'dd-Month-yyyy HH24:MI:ss')
