Dear members,
I hope I'm in the correct thread. I found the commit 1fd1bd8 - it is so cool.
I have a question for it.
ISTM commit message said that no need to do ANALYZE again.
```
Add support to pg_dump for dumping stats, and use that during
pg_upgrade so that statistics are transferred during upgrade. In most
cases this removes the need for a costly re-analyze after upgrade.
```
But pgupgrade.sgml [2] and source code [3] said that statistics must be updated.
Did I miss something, or you have been updating this?
[2]:
```
Because optimizer statistics are not transferred by <command>pg_upgrade</command>, you will
be instructed to run a command to regenerate that information at the end
of the upgrade. You might need to set connection parameters to
match your new cluster.
```
[3]:
```
pg_log(PG_REPORT,
"Optimizer statistics are not transferred by pg_upgrade.\n"
"Once you start the new server, consider running:\n"
" %s/vacuumdb %s--all --analyze-in-stages", new_cluster.bindir, user_specification.data);
```
