* feat(cli): add `migrate` subcommand for generating a build script
suggest embedding migrations on `sqlx migrate add` in a new project
* a task that is marked woken but didn't actually wake before being cancelled will instead wake the next task in the queue
* a task that wakes but doesn't get a connection will put itself back in the queue instead of waiting until it times out with no way to be woken
* the idle reaper now won't run if there are tasks waiting for a connection, and also uses
the proper `SharedPool::release()` to return validated connections to the pool so waiting tasks get woken

(hopefully for good this time)

Fix commit updates the `postgres::connection::describe` module to add full support for domain types. Domain types were previously confused with their category which caused invalid oid resolution.
Fixeslaunchbadge/sqlx#110
BREAKING CHANGE: some columns in `query!()` et. al. output will change from `T` to `Option<T>`
breakage should be minimal in practice as
these columns will need to have been manually
overridden anyway to avoid runtime errors

This solves a problem when needing to describe a query before executing
it, in cases where the query is more of a dynamic nature and binding its
parameters require the type info.
In this case, the first describe doesn't know the input parameters, so
the parameter type info is inferred from the database. In cases of
`varchar(10)[]` or `json` column types, the parameter type is inferred
to the column type. Now if we then try to use `text[]` or `jsonb` as the
types, the database has already stored different types for these
parameters for the statement, and will error out.
So we'll now only store the statement to the cache when it comes from an
actual execution of the query.
