Hello, 

Unfortunately I was not able to reproduce this issue. Did you upgrade from version prior to 5.2 (like 4.*) so that your database had several upgrades? Any specific settings?

Usually minor version upgrade comes with no problem.

The concerning upgrade step was from 5.2.6 to 5.4.0.

We are using zabbix since v2.2 and have been constantly upgrading though the versions. With the upgrade from 4.x to 5.x I furthermore switched from a partitioned MySQL to PostgreSQL with timescaleDB.

As this issue seems to be caused by faulty and/or missing indicies and tablefields I attached our DB scheme to this ticket.

I noticed the database script was only trying to drop the index users_1, so I resolved the issue by simply creating the missing index users_1 (and adding another index called httptest_1, because it was also missing):

CREATE INDEX users_1 ON users (userid);
CREATE INDEX httptest_1 on httptest (httptestid);

Afterwards the database upgrade succeeded.
