:(.  s/no longer/still.  I meant to say any one of those WAL files will not be archived and recycled as long as it still needed by a replication slot.


A WAL segment will be archived as soon as it is completed. https://www.postgresql.org/docs/11/continuous-archiving.html


Yep, you’re right. Let me try this again. It will be archived, but the segment won’t be reused or removed as long as the slot needs it. Is that an accurate statement?

Thanks,
Jeremy
