PG-15.6: timeout parameters erroring out

[Mukesh Tanuku <mukesh.postgres@xxxxxxxxx>]

Hello team,

We unabled the postgres timeout parameters in the postgresql.conf file

idle_in_transaction_session_timeout = '1min'
idle_session_timeout = '5min'

other way also, like below 

idle_in_transaction_session_timeout = 60000
idle_session_timeout = 300000

we see these errors reporting in the logs after we enabled those parameters

log:

2025-02-10 04:17:19.156 GMT [2467573] ERROR:  trailing junk after numeric literal at or near "1m" at character 43

Is there any know issue/bug with these paramters, can someone help me to get this worked since our app idle connections are getting pilled up and reaching max connections. 

I really appreciate your help. Thank you.

Regards
