+     The default is true.  If true, VACUUM frees empty pages at the end of the table.

+     It can take non-negligible time when the shared buffer is large.  Besides, <literal>ACCESS EXCLUSIVE</literal>
+     lock could lead to query cancellation on the standby server.
+     If the workload is likely to reuse the freed space soon
+     (e.g., UPDATE-heavy, or new rows will be added after deleting
+     old rows), setting this parameter to false makes sense to avoid unnecessary shrinking.
+      This parameter cannot be set for TOAST tables.
