Broken FOSS master due to EE-only JSONB schema validations
Summary
We introduced !33641 (merged), and it was fine.
Follow-up work on #222826 (closed)
This commit: 05c76158
broke the -foss build only: gitlab-foss@12866a39
because the validator only exists in EE, but the database column exists in both.
For the moment, I'll push a commit that adds this column to the list of allowed "without schema" columns, to get us green again, but we need to think about how to solve this more generally.
