The error fires when COMMIT or ROLLBACK is issued outside a valid transaction block or after a transaction is already aborted.
invalid_transaction_termination appears when PostgreSQL receives COMMIT or ROLLBACK while no valid BEGIN block is active. Start a transaction with BEGIN before committing or remove the stray terminator to resolve the error.
invalid_transaction_termination
PostgreSQL raises the 2D000 invalid_transaction_termination error when a COMMIT, ROLLBACK, or END command is executed while no matching transaction block is active. The server halts the statement to safeguard data integrity.
Scripts that mix autocommit sessions with manual transaction control or PL/pgSQL functions that finish prematurely often trigger this message.
Correcting the transaction flow eliminates the exception.
A COMMIT issued without a preceding BEGIN immediately fails because there is no open transaction to finish.
The same logic applies to ROLLBACK and END.
If a previous SQL error has marked the transaction as aborted, PostgreSQL refuses COMMIT and instead requires ROLLBACK, resulting in invalid_transaction_termination when COMMIT is attempted.
Calling COMMIT inside a PL/pgSQL function that already runs inside a caller's transaction also produces the error, since nested commits are prohibited.
Start explicit work with BEGIN and end with COMMIT or ROLLBACK, ensuring each terminator has a partner.
Avoid mixing explicit control with autocommit in the same script.
When the transaction is in an aborted state (25P02), issue ROLLBACK first, then begin a fresh transaction before resuming operations.
Remove COMMIT or ROLLBACK from stored procedures unless the function is declared to run autonomously. Let the caller control the overarching transaction.
psql scripts run with autocommit on often end with a stray COMMIT.
Delete that line or disable autocommit (set AUTOCOMMIT off) to match BEGIN .. COMMIT pairs.
Java programs that call connection.setAutoCommit(false) without a corresponding commit() cause 2D000 when other frameworks attempt to close the connection. Always wrap JDBC calls in try/finally.
PL/pgSQL functions that swallow exceptions can leave the session in a failed transaction state.
Add a RAISE or explicit ROLLBACK in EXCEPTION blocks.
Adopt a single transaction strategy per application component: either rely on autocommit or manage BEGIN/COMMIT explicitly, not both.
Use code reviews and linting to forbid unmatched COMMIT or ROLLBACK.
Galaxy highlights unmatched transaction delimiters and suggests AI fixes.
Add defensive checks such as SHOW transaction_isolation or SELECT txid_current() during development to verify the expected scope.
25P02 in_failed_sql_transaction - occurs when any command follows an error inside a transaction. Issue ROLLBACK first.
2D000 invalid_transaction_state - similar but triggered by commands other than commit/rollback after the transaction aborted.
Clear with ROLLBACK.
0Z002 stacked_diagnostics_accessed_without_active_handler - raised when GET STACKED DIAGNOSTICS is used outside an exception block; review PL/pgSQL handlers.
.
Yes. In psql run \set AUTOCOMMIT off, then manage BEGIN and COMMIT manually. Ensure every transaction ends with COMMIT or ROLLBACK.
PostgreSQL flags the transaction as aborted when any error occurs. COMMIT is disallowed because the work is no longer consistent. Roll back first.
PostgreSQL supports SAVEPOINT for partial rollbacks but still requires one outer COMMIT. Avoid calling COMMIT inside a function.
Galaxy's editor warns about unmatched transaction commands and its AI copilot rewrites scripts to maintain correct BEGIN..COMMIT structure, preventing the error.
