Hi,
This works in Postgres 15:
pg15> create function json_test(out value text, out json jsonb)
returns record
language sql
as
$$
select null::text, null::jsonb;
$$
;
CREATE FUNCTION
pg15> select * from json_test();
┌───────┬──────┐
│ value │ json │
├───────┼──────┤
│ │ │
└───────┴──────┘
(1 row)
In Postgres 17 trying to create the function yields an error:
pg17> create function json_test(out value text, out json jsonb)
returns record
language sql
as
$$
select null::text, null::jsonb;
$$
;
ERROR: syntax error at or near "jsonb"
LINE 1: create function json_test(out value text, out json jsonb)
Am I doing something wrong? Or is this a regression?
Yes you are doing something wrong, naming an argument with a type
name(json) is not a good idea. Guessing you got caught by this:
https://www.postgresql.org/docs/16/sql-keywords-appendix.html
JSON non-reserved reserved
https://www.postgresql.org/docs/17/sql-keywords-appendix.html
JSON non-reserved (cannot be function or type) reserved
Thanks,
Colin
