+ A dump/restore is not required for those running 12.X.
+ However, note that installations using physical replication should
update standby servers before the primary server, details in the
release notes linked below.
+ Also, several bugs have been found that may have resulted in corrupted
indexes, explained in detail in the release notes linked below. If any
of those cases apply to you, it's recommended to reindex
possibly-affected indexes after updating.
+ Also, if you are upgrading from a version earlier than 12.6,
see those release notes as well please.
+ Details about these and many further changes can be found at:
