Hi I have posted this problem on kdepim-users list but with no resolution. A little history. I changed from mysql to postgresql a long time ago when ver 9.6 was the latest version of postgres. I've update the DB to 10, 11, 12 until ver 13 which i have been using until now. I did try updating to ver 14 but it failed with locale issues during the update and i couldn't get a resolution. I just recently managed to get the database converted from postgresql13 to postgresql16 and the data was transferred to the new DB with no issues. I can't get akonadi loaded as it fails starting postgresql, its failing with a message saying it needs ver 9.6 as teh DB was created using 9.6. I can't see why it insists on ver 9.6 being there as i've updated to ver 16 and that process means i create an empty DB. Ver 9.6 doesn't seem to be in the repos anymore for me to even reinstall it. Thanks for any help.
