Failure to build with `opaleye-0.9.3.0`

[jkachmar]

It looks like opaleye removed the stateQueryArr function in 0.9.3.0 (cf. https://github.com/tomjaguarpaw/haskell-opaleye/commit/01f2b37b9d5d03236e97399dc99b5520ccf41e73).

rel8 now fails to compile with the following error:

Preprocessing library for rel8-1.3.1.0..

Thanks @jkachmar! @tomjaguarpaw do you plan to bring stateQueryArr back, or shall we adapt Rel8?

[tomjaguarpaw]

Oh whoops. I added back the bits I removed in https://hackage.haskell.org/package/opaleye-0.9.3.1. At some point we should convert Rel8 to the new way, but it's not urgent.

[ocharles]

Much appreciated, thanks!

Fixed in master - will cut a release soon!
