PostgresDB 25001: Active SQL Transaction

What is PostgresDB 25001: Active SQL Transaction

When encountering error 25001: Active SQL Transaction in Postgres, the user should immediately execute the following actions for investigation:

Identify Active Transactions:SELECT * FROM pg_stat_activity WHERE state IN ('active', 'idle in transaction');Check for Long-Running Queries:SELECT pid, now() - pg_stat_activity.query_start AS duration, query, stateFROM pg_stat_activityWHERE (now() - pg_stat_activity.query_start) > interval '5 minutes';Terminate Long-Running Transactions if Necessary (Caution Advised):SELECT pg_terminate_backend(pid)FROM pg_stat_activityWHERE pid = [PID of the transaction to terminate];Replace [PID of the transaction to terminate] with the actual PID of the problematic transaction.Analyze Locks That Might Be Causing Issues:SELECT bl.pid AS blocked_pid, a.usename AS blocked_user, kl.pid AS blocking_pid, ka.usename AS blocking_user, a.query AS blocked_queryFROM pg_catalog.pg_locks blJOIN pg_catalog.pg_stat_activity a ON a.pid = bl.pidJOIN pg_catalog.pg_locks kl ON kl.transactionid = bl.transactionid AND kl.pid != bl.pidJOIN pg_catalog.pg_stat_activity ka ON ka.pid = kl.pidWHERE NOT bl.granted;

These steps should help in identifying the cause of the “Active SQL Transaction” error and potentially resolving it by terminating any problematic transactions or addressing locking issues.
