Adding test for table schedulingobjects and fixing postgres LOB

[janLo]

This is a fix for #8825. It was fixed in Owncloud in owncloud/core@afd4ebf So this is just a cherry-pick of that fix.

LGTM, not tested.

@janLo could you signoff your commit, so that the checker test passes?

[janLo]

Are you sure, that I should sign off the work from another person? Shouldn't be the original commit be signed in the first place?

@janLo you don't have to be the copyright owner to sign the commit. By signing you just declare:

    indicated in the file; or

(b) The contribution is based upon previous work that, to the best
    of my knowledge, is covered under an appropriate open source
    license and I have the right under that license to submit that
    work with modifications, whether created in whole or in part
    by me, under the same open source license (unless I am
    permitted to submit under a different license), as indicated
    in the file; or

(c) The contribution was provided directly to me by some other

So if you copied the fix from the public repository of ownCloud and checked that it is licensed under a compatible license then it is absolutely OK to sign it. Actually that's the purpose, you basically say that you checked "to the best of my knowledge" that you can contribute the code to Nextcloud under the license used by Nextcloud.

[janLo]

done.
