Plan for exclusive backup method

[MEERA <meeranair89@xxxxxxxxx>]

Hi team, 

https://www.postgresql.org/docs/12/continuous-archiving.html

It is mentioned here that exclusive backup method is deprecated and should be avoided. it is now recommended that all users upgrade their scripts to use non-exclusive backups.

Does this mean select pg_start_backup('label', false, true) is deprecated?

In a future version, will it not allow the third argument to be true?
