So it doesn't look like a good solution. I am more concentrated on the Pg 14 release, where the work with SPI is redesigned, and I hope so this issue is fixed there. For older releases, I don't know. Is this issue related to Postgres or it is related to PgPro only? If it is related to community pg, then we should fix and we should accept not too good performance, because there is no better non invasive solution. If it is PgPro issue (because there are ATX support) you can fix it (or you can try backport the patch https://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=ee895a655ce4341546facd6f23e3e8f2931b96bf ). You have more possibilities on PgPro code base.Sorry, it is not PgPro specific problem and recent master suffers from this bug as well. In the original bug report there was simple scenario of reproducing the problem: CREATE TABLE toasted(id serial primary key, data text); INSERT INTO toasted(data) VALUES((SELECT string_agg(random()::text,':') FROM generate_series(1, 1000))); INSERT INTO toasted(data) VALUES((SELECT string_agg(random()::text,':') FROM generate_series(1, 1000))); DO $$ DECLARE v_r record; BEGIN FOR v_r in SELECT data FROM toasted LOOP INSERT INTO toasted(data) VALUES(v_r.data);COMMIT;END LOOP;END;$$; can you use new procedure_resowner?
Sorry, I do not understanf your suggestion. How procedure_resowner can help to solve this problem? -- Konstantin Knizhnik Postgres Professional: http://www.postgrespro.com The Russian Postgres Company
