PostgreSQL Data Types
------------------------
As with all SQLAlchemy dialects, all UPPERCASE types that are known to be
valid with Postgresql are importable from the top level dialect, whether
they originate from :mod:`sqlalchemy.types` or from the local dialect::
from sqlalchemy.dialects.postgresql import \
ARRAY, BIGINT, BIT, BOOLEAN, BYTEA, CHAR, CIDR, DATE, \
DOUBLE_PRECISION, ENUM, FLOAT, INET, INTEGER, INTERVAL, \
MACADDR, NUMERIC, REAL, SMALLINT, TEXT, TIME, TIMESTAMP, \
UUID, VARCHAR
Types which are specific to PostgreSQL, or have PostgreSQL-specific
construction arguments, are as follows:
.. currentmodule:: sqlalchemy.dialects.postgresql
.. autoclass:: array
.. autoclass:: ARRAY
:members: __init__
:show-inheritance:
