error-handling

To use ereport correctly for PostgreSQL backend error reporting, you must enforce proper severity levels, select appropriate SQLSTATE codes, and format messages for gettext compatibility. This ensures transaction-safe logging and prevents system resource leaks during longjmp handling.

The difference between ereport and elog in PostgreSQL C source lies in their use cases: ereport is for user-facing messages requiring SQLSTATE codes and gettext formatting, while elog is typically for internal logging. Correct selection prevents transaction abort failures and memory corruption.

To prevent memory leaks in PostgreSQL PG_TRY/PG_CATCH blocks, you must follow strict resource management and memory context rules. Safe handling prevents memory corruption and transaction abort failures caused by unsafe longjmp jumps during backend error reporting.

PostgreSQL backend development requires specific error handling idioms including adherence to internal coding conventions for memory context management, correct SQLSTATE selection, and standardized message formatting to ensure transaction safety and prevent system resource mismanagement.

Your PostgreSQL ereport call might cause a transaction abort failure due to improper error severity levels, unsafe longjmp handling, or incorrect memory context management. Enforcing correct PG_TRY/PG_CATCH blocks and resource cleanup rules resolves this.
