When encountering the error 25002: Branch Transaction Already Active in a Postgres database, the user should:
SELECT * FROM pg_stat_activity WHERE state = 'active';
to identify active transactions.SELECT pid, now() - pg_stat_activity.query_start AS duration, query FROM pg_stat_activity WHERE state = 'active' ORDER BY duration DESC;
to find long-running queries that might be causing the issue.SELECT pg_terminate_backend(pid);
where pid
is the process ID of the transaction to be terminated.Immediate action involves identifying and potentially terminating problematic transactions, and reviewing application logic for transaction handling.
