Hi,

When the first example of the https://www.postgresql.org/docs/12/plpgsql-transactions.html:

--run before:

--create table test1(a int);

CREATE PROCEDURE transaction_test1()

LANGUAGE plpgsql

AS $$

BEGIN

    FOR i IN 0..9 LOOP

        INSERT INTO test1 (a) VALUES (i);

        IF i % 2 = 0 THEN

            COMMIT;

        ELSE

            ROLLBACK;

        END IF;

    END LOOP;

END;

$$;

CALL transaction_test1();

The CALL fails with error:

ERROR: invalid transaction termination

CONTEXT: PL/pgSQL function transaction_test1() line 6 at COMMIT

SQL state: 2D000

The exact version of PostgreSQL: PostgreSQL 12.7 (Ubuntu 12.7-0ubuntu0.20.04.1) on x86_64-pc-linux-gnu, compiled by gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0, 64-bit

I copy and paste your example, and it works for me. And the contents of the table look good to me:

$ psql
Time: 4.458 ms
psql (12.7)
Type "help" for help.

postgres@r12 =# truncate test1;
TRUNCATE TABLE
Time: 6.504 ms
postgres@r12 =# CALL transaction_test1();
CALL
Time: 15.540 ms
postgres@r12 =# TABLE test1;
┌───┐
│ a │
├───┤
│ 0 │
│ 2 │
│ 4 │
│ 6 │
│ 8 │
└───┘
(5 rows)

Time: 0.948 ms

There must be something else on your side that makes it fail.
