Hi,  
I am testing Discourse upgrade from version 3.0.3 to 3.0.4. After the upgrade Discourse is running, but after login to the system most of the pages/requests end up with 500 error.  
In log files I see two different errors:

```plaintext
Job exception: PG::SyntaxError: ERROR: zero-length delimited identifier at or near """" LINE 1: ...1003061, "success" = TRUE WHERE "scheduler_stats"."" IS NULL

```

and

```plaintext

```

When I downgrade system back to 3.0.3 everything works fine.

We are not using many plugins, but I also did one attempt with all plugins disabled. Same result.

Thanks in advance for any help.

3.2 stable is imminent. I would not bother with upgrading until that’s announced.

3.0.x is unlikely to be supported by many plugins and theme components.

Sorry, my mistake there. Upgrade I have troubles with is from 3.1.3 to 3.1.4. Motivation is to address CVEs fixed in 3.1.4.
