Perhaps a module_invoke_all('schema') in an update hook and renaming the relevant lowercase-only fields to reflect the capitalization in the schema definitions? Fixing that now + copying over the issue summary. That should be easy. Note: This tag should generally remain even after the backport has been written, approved, and committed.

So then when he created using uppercase, it stuck, but then when he queried using uppercase, it got lowercased and didn't work. One could argue that an array property be added and is a better place to store this information: The reason for the double quotes is to add compatibility for querying third party databases that use this convention. Needs a run on a pgsql testbot - all tests or database + node revision tests. Does English have an equivalent to the Aramaic idiom "ashes on my head"?
