## Problem See https://github.com/neondatabase/company_projects/issues/111 ## Summary of changes Save logical replication files in WAL at compute and include them in basebackup at pate server. ## Checklist before requesting a review - [ ] I have performed a self-review of my code. - [ ] If it is a core feature, I have added thorough tests. - [ ] Do we need to implement analytics? if so did you add the relevant metrics to the dashboard? - [ ] If this PR requires public announcement, mark it with /release-notes label and add several sentences in this section. ## Checklist before merging - [ ] Do not forget to reformat commit message to not include the above checklist --------- Co-authored-by: Konstantin Knizhnik <knizhnik@neon.tech> Co-authored-by: Arseny Sher <sher-ars@yandex.ru>
