Reduce serialization errors in MultiWriterIdGen (#8456) 
We call `_update_stream_positions_table_txn` a lot, which is an UPSERT
that can conflict in `REPEATABLE READ` isolation level. Instead of doing
a transaction consisting of a single query we may as well run it outside
of a transaction.

e48ba84e0b Check postgres version in check_database 
this saves doing it on each connection, and will allow us to pass extra options
in.

e97d1cf001 Modify check_database to take a connection rather than a cursor 
We might not need the cursor at all.

1d3858371e Disable bytes usage with postgres 
More often than not passing bytes to `txn.execute` is a bug (where we
meant to pass a string) that just happens to work if `BYTEA_OUTPUT` is
set to `ESCAPE`. However, this is a bit of a footgun so we want to
instead error when this happens, and force using `bytearray` if we
actually want to use bytes.

Store state groups separately from events (#2784) 
* Split state group persist into seperate storage func

* Add per database engine code for state group id gen

* Move store_state_group to StateReadStore

This allows other workers to use it, and so resolve state.

* Hook up store_state_group

* Fix tests

* Rename _store_mult_state_groups_txn

* Rename StateGroupReadStore

* Remove redundant _have_persisted_state_group_txn

* Update comments

* Comment compute_event_context

* Set start val for state_group_id_seq

... otherwise we try to recreate old state groups

* Update comments

* Don't store state for outliers

* Update comment

* Update docstring as state groups are ints

d5fb561709 Optionally make committing to postgres asynchronous. 
Useful when running tests when you don't care whether the server
will lose data that it claims that it has committed.
