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?
