The pg8000 dialect has been revised and modernized for the most recent
version of the pg8000 driver for PostgreSQL. Changes to the dialect
include:
* All data types are now sent as text rather than binary.
* Using adapters, custom types can be plugged in to pg8000.
* Previously, named prepared statements were used for all statements.
Now unnamed prepared statements are used by default, and named
prepared statements can be used explicitly by calling the
Connection.prepare() method, which returns a PreparedStatement
object.
Pull request courtesy Tony Locke.
Notes by Mike: to get this all working it was needed to break
up JSONIndexType into "str" and "int" subtypes; this will be
needed for any dialect that is dependent on setinputsizes().
also includes @caselit's idea to include query params
in the dbdriver parameter.

We want TOX_POSTGRESQL and similar to be the fixed variable
that is configured from CI environment. These variables should refer
to database servers but individual drivers like asyncpg mysqlconnector
etc. should come from local tox.ini. add a new system to generate
per-driver URLs from a simple list of hostname-based URLs delivered
from CI environment.

Execution of literal sql string is deprecated in the
:meth:`.Connection.execute` and a warning is raised when used stating
that it will be coerced to :func:`.text` in a future release.
To execute a raw sql string the new connection method
:meth:`.Connection.exec_driver_sql` was added, that will retain the previous
behavior, passing the string to the DBAPI driver unchanged.
Usage of scalar or tuple positional parameters in :meth:`.Connection.execute`
is also deprecated.

1. ensure provision.py loads dialect implementations when running
reap_dbs.py. Reapers haven't been working since
598f2f7e557073f29563d4d567f43931fc03013f .
2. add some exclusion rules to allow the sqlite_file target to work;
add to tox.
3. add reap dbs target for SQLite, repair SQLite drop_db routine
which also wasn't doing the right thing for memory databases
etc.
4. Fix logging in provision files, as the main provision logger
is the one that's enabled by reap_dbs and maybe others, have all
the provision files use the provision logger.
