Hi all,
I am using cursors to fetch the data from table using C++. Initially were errors as highlighted as "current transaction isaborted" in /var/logs during full vacuum. We are little bit confused in failure handling. In case of any failure of following function. PQexec(connection, myFetchSql) We have to close the cursor or rollback the transaction? postgres[10709]: [6-1] < 2019-10-29 11:24:22.550 CET > ERROR: canceling statement due to conflict with recovery postgres[10709]: [6-2] < 2019-10-29 11:24:22.550 CET > DETAIL: User query might have needed to see row versions that must be removed. postgres[10709]: [6-3] < 2019-10-29 11:24:22.550 CET > STATEMENT: FETCH 1000 IN mycursor_3461662464_1572368715367985819 postgres[10709]: [7-1] < 2019-10-29 11:24:22.550 CET > ERROR: current transaction is aborted, commands ignored until end of transaction block postgres[10709]: [7-2] < 2019-10-29 11:24:22.550 CET > STATEMENT: CLOSE mycursor_3461662464_1572368715367985819 O Regards Tarkeshwar
