Add indices support (WIP)

## Motivation Currently, there is no way to deal with the database schema purely via Haskell code, which is not good at least because when we define our schema in...

According to [this](https://stackoverflow.com/questions/3207647/ghc-refuses-to-export-qualified-modules) question this code https://github.com/haskell-beam/beam/blob/4ed616fdd9f0431a8ce634733bd6d43fed05b173/beam-postgres/examples/Pagila/Schema/V0002.hs#L7-L13 re-exports nothing from V0001 module, thus we have no access to datatypes that are declared in V0001 wherever we import `Pagila.Schema` module

DEFAULT can appear in arbitrary expressions

`DEFAULT` should only be able to appear in the `VALUES` clause of an `INSERT INTO` statement, not in any arbitrary expresion.

Export generic classes

`beam` relies very heavily on GHC generics, but the standard GHC generic instances are not appropriate for all use cases (motivating example in this case being [`large-records`](https://hackage.haskell.org/package/large-records)). Fortunately, the way...

Heard there was a major release cycle coming :). This would resolve #491. Note: I used an `unsafeCoerce` to implement these. I think it's fine and the tests pass, but...
