Hello, I upgraded to pgAdmin 4 v7 (from v3 I think) on Windows and I cannot start pgAdmin any more, the fatal error says:
2023-06-05 09:51:58,190: ERROR pgadmin: Database migration failed
2023-06-05 09:51:58,194: ERROR pgadmin: Traceback (most recent call last):
File "C:\Users\Mark\AppData\Local\Programs\pgAdmin 4\v7\python\lib\site-packages\alembic\operations\batch.py", line 692, in drop_constraint
const = self.named_constraints.pop(
const.name)
KeyError: 'ck_port_range'
I cannot find any reference to this error in the mail list archives or online. Any help would be appreciated....
