Erro upgrade 3.3.0-17 to 3.4.0-7

Dear all,
I’m trying to update OJS with postgres and the following error is occurring:

2024-10-17 11:51:49 [migration: PKP\migration\upgrade\v3_4_0\I7249_UpdateUsersUniqueIndex]
2024-10-17 11:51:49 [revert migration: APP\migration\upgrade\v3_4_0\I7470_FixDeprecatedFileStage]
2024-10-17 11:51:49 [downgrade for "APP\migration\upgrade\v3_4_0\I7470_FixDeprecatedFileStage" unsupported: Downgrade not supported]
ERROR: Upgrade failed: DB: SQLSTATE[42704]: Undefined object: 7 ERROR:  constraint "users_username" of relation "users" does not exist (SQL: ALTER TABLE users DROP CONSTRAINT users_username;)

What could I do about it?

Did you check this?
