can not use ArrayField when I imort PostgresqlExtDatabase?
Um...are you referencing `ArrayField` somewhere in your module? `ArrayField` is defined in `playhouse.postgres_ext` so to use it you'll need to import it along with `PostgresqlExtDatabase`. after that, I import ArrayField with:
from playhouse.postgres_ext import ArrayField

that say:"peewee.ProgrammingError: hstore type not found in the database. please install it from your 'contrib/hstore.sql' file"

thanks
 other wise:
I did not use 'hstore' That is ok， NOW！！

i forgot add hstore extension
use ‘ create extension hstore’

when I import PostgresqlExtDatabase like this:
 from playhouse.postgres_ext import PostgresqlExtDatabase

that say:"NameError: name 'ArrayField' is not defined"


thanks
