$ pip install minipg
Example
Query:
import minipg conn = minipg.connect(host='localhost', user='postgres', password='secret', database='database_name') cur = conn.cursor() cur.execute('select foo, bar from baz') for r in cur.fetchall(): print(r[0], r[1]) conn.close()
COPY TO:
import minipg conn = minipg.connect(host='localhost', user='postgres', password='secret', database='database_name') f = open('foo.txt', 'bw') conn.execute('COPY foo_table TO stdout', f) f.close() conn.close()
COPY FROM:
import minipg conn = minipg.connect(host='localhost', user='postgres', password='secret', database='database_name') f = open('foo.txt', 'br') conn.execute('COPY foo_table FROM stdin', f) f.close() conn.close()
As sqlalchemy dialect:
from sqlalchemy.dialects import registry registry.register("postgresql.minipg", "minipg.dialect", "PGDialect_minipg") from sqlalchemy import create_engine engine = create_engine('postgresql+minipg://postgres:secret@host/database_name')
