Anyway bigint problem is the next in the line.
Yeah it is related to this:
https://www.postgresql.org/docs/11/functions-array.html
unnest(anyarray) setof anyelement
Dealing with anyelement can be tricky.
I tried out an alternate solution:
json_query = "select * from json_to_recordset(%s) as t(a timestamp, b
varchar, c bigint)"
cur.execute(json_query,[Json([{'a': datetime.now().isoformat(), 'b':
'abc', 'c': 100},{'a': datetime.now().isoformat(), 'b': 'xyz', 'c':
200}])])
Should have added that Json comes from:
from psycopg2.extras import Json
http://initd.org/psycopg/docs/extras.html?highlight=json#json-adaptation
Which results in:
test_(postgres)# select * from json_to_recordset(E'[{"a":
"2019-12-04T10:40:22.823910", "b": "abc", "c": 100}, {"a":
"2019-12-04T10:40:22.823918", "b": "xyz", "c": 200}]') as t(a timestamp,
b varchar, c bigint)
;
a | b | c
----------------------------+-----+-----
2019-12-04 10:40:22.82391 | abc | 100
2019-12-04 10:40:22.823918 | xyz | 200
