does postgres has snapshot standby feature?

[milist ujang <ujang.milist@xxxxxxxxx>]

hi all,

read about removing standby.signal file behavior in pg14 from 

https://dbaclass.com/article/how-to-open-postgres-standby-database-for-read-writesnapshot-standby/

I was shocked about the hidden feature of snapshot standby, does it really exist?

I could not find anything about snapshot standby in docs so far.

I have removed the standby.signal file in pg12 but got strange behavior until I have to recreate the standby.
