py-peewee: updated to 3.9.0

New and improved stuff
Added new document describing how to use peewee interactively.
Added convenience functions for generating model classes from a pre-existing \ 
database, printing model definitions and printing CREATE TABLE sql for a model. \ 
See the "use peewee interactively" section for details.
Added a __str__ implementation to all Query subclasses which converts the query \ 
to a string and interpolates the parameters.
Improvements to sqlite_ext.JSONField regarding the serialization of data, as \ 
well as the addition of options to override the JSON serialization and \ 
de-serialization functions.
Added index_type parameter to Field
Added DatabaseProxy, which allows one to use database-specific decorators with \ 
an uninitialized Proxy object.
Added support for INSERT ... ON CONFLICT when the conflict target is a partial \ 
index (e.g., contains a WHERE clause). The OnConflict and on_conflict() APIs now \ 
take an additional conflict_where parameter to represent the WHERE clause of the \ 
partial index in question.
Enhanced the playhouse.kv extension to use efficient upsert for all database \ 
engines. Previously upsert was only supported for sqlite and mysql.
Re-added the orwhere() query filtering method, which will append the given \ 
expressions using OR instead of AND.
Added some new examples to the examples/ directory
Added select_from() API for wrapping a query and selecting one or more columns \ 
from the wrapped subquery. Docs.
Added documentation on using row values.
Removed the (defunct) "speedups" C extension, which as of 3.8.2 only \ 
contained a barely-faster function for quoting entities.

Fix bug in SQL generation when there was a subquery that used a common table \ 
Enhanced prefetch() and fixed bug that could occur when mixing self-referential \ 
foreign-keys and model aliases.
MariaDB 10.3.3 introduces backwards-incompatible changes to the SQL used for \ 
upsert. Peewee now introspects the MySQL server version at connection time to \ 
ensure proper handling of version-specific features.
Fixed bug where TimestampField would treat zero values as None when reading from \ 
the database.
