When upgrading Portal 10.5.1 to 10.6 I get the following error message in the log:
lc_collate values for database "postgres" do not match: old "Swedish_Sweden.1252", new "English_United States.1252"
Failure, exiting
Failed to upgrade the PostgreSQL from 9.3.12 to 9.6.3.
Someone else having the same problem?
