[bug\_fix] ERROR: current transaction is aborted, commands ignored until end of transaction block \(SQLSTATE 25P02\)

Issue a \`ROLLBACK\` \(or \`ROLLBACK TO SAVEPOINT\`\) to clear the aborted state before executing new commands. In application code using an ORM \(Django, SQLAlchemy\), ensure the error handler rolls back the transaction before re-raising or attempting recovery logic.

Journey Context:
Django view tries to insert a record with a duplicate key, triggering IntegrityError. The exception is caught in a try/except block, logged, and the code attempts to query a reference table to return a friendly error message. Instead, it gets "current transaction is aborted". Developer learns that in PostgreSQL, any error within a transaction puts it into an "aborted" state where all subsequent commands are ignored until a ROLLBACK. The fix is to ensure the ORM \(Django's \`transaction.atomic\(\)\`\) performs a rollback in the exception handler before new queries, or to manually execute \`connection.rollback\(\)\`.

environment: Web applications using ORMs \(Django, SQLAlchemy, ActiveRecord\) with explicit transaction blocks or auto-commit disabled, where errors are caught and handled within the transaction. · tags: postgres aborted-transaction 25p02 rollback transaction-block error-handling orm · source: swarm · provenance: https://www.postgresql.org/docs/current/plpgsql-error-trapping.html
