Thanks. I did \l before which gives:
List of databases
Name | Owner | Encoding | Collate | Ctype | ICU Locale | Locale Provider | Access privileges
------------+----------+----------+-------------+-------------+------------+-----------------+-----------------------
bar | foo | UTF8 | de_DE.UTF-8 | de_DE.UTF-8 | | libc |
customers | sisis | UTF8 | de_DE.UTF-8 | de_DE.UTF-8 | | libc |
...
But why the ALTER statement needs the spelling different as the output of \l :
sisis=# ALTER COLLATION "de_DE.UTF-8" REFRESH VERSION;
ERROR: collation "de_DE.UTF-8" for encoding "UTF8" does not exist
sisis=# ALTER COLLATION "de_DE.utf8" REFRESH VERSION;
NOTICE: version has not changed
ALTER COLLATION
?

That REINDEX is certainly correct, even though it rebuilds way more
indexes than necessary.
If the ALTER COLLATION statement is correct or not depends on the
collation you are using. You could look at "\l" and "pg_collation"
to get the name right.
