The statement looks incorrect from the python point of view (not just
plpython). You should quote multi-lined strings, or use an escape
character (\) like:
"""line 1
line 2"""
'''line 1
line2'''
'line 1\n\
line2'
So I would try to rewrite the statement with:
sql = """INSERT INTO table1 (field1, field2, field3)
VALUES ('abc', 'abc', TRUE),
('def', 'def', FALSE),
('ghi', 'ghi', TRUE);"""
pypl.execute(sql)
