Re: [sqlalchemy] Postgresql JSON object update.
You can use the "op" method:
https://docs.sqlalchemy.org/en/14/core/sqlelement.html#sqlalchemy.sql.expression.Operators.op
some_column.op("||")(other_column)
Hope that helps,
Simon

[sqlalchemy] Postgresql JSON object update.
In postgresql the || operator is the only way (no, the concat() function
doesn't work) to concat 2 JSONB dicts; note that this works only with JSONB
and not JSON.
Example:
suppose column "t.c" contains '{"a": 1}'::jsonb
SELECT t.c || jsonb_build_object('b', 2);
gives
{"a": 1, "b": 2}
Question: How can I obtain the || operator in sqlalchemy (core, 1.3) to
merge 2 JSONB dicts?
