The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/16/app-pgrewind.html Description:
After the sentence "all other files, including new relation files, configuration files, and WAL segments, are copied in full." we should add "However, no files are copied if there is no divergence, i.e. if the source data directory is found to be compatible with the target data directory: in that case pg_rewind exits successfully without performing the synchronization."
