+# This test demonstrates effect of relpersistence cache. Postgres doesn't store relation persistence in shared buffer tag.
 # It means that if page is evicted from shared buffers and relation is not cache in relation cache, then persistence=0 (auto) is used.
 # For vanilla Postgres it is not important, because in both cases we need to write changes to the file.
 # In Neon, neon_write does nothing nothing for a permanent relation, while for an unlogged relation, it writes the page to the local file.
