Thanks. I tried a lot of combinations. Based on the output of \l

                                                  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            |
...

postgres=# ALTER COLLATION "de_DE.UTF8" REFRESH VERSION;
ERROR:  collation "de_DE.UTF8" for encoding "UTF8" does not exist

yours (Dominique) seems to work:

postgres=# ALTER COLLATION "de_DE.utf8" REFRESH VERSION;
NOTICE:  version has not changed
ALTER COLLATION

If I understand the other reply from Laurenz Albe right, the correct
procedure would be:

pgsql -Usisis sisis

sisis=# REINDEX (VERBOSE) DATABASE sisis;
sisis=# ALTER COLLATION "de_DE.utf8" REFRESH VERSION;
ALTER COLLATION

Correct?
