Plan C would be something like if (num_held_lwlocks >= MAX_SIMUL_LWLOCKS) { release the acquired lock; elog(ERROR, "too many LWLocks taken"); } But we couldn't just call LWLockRelease, since it expects the lock to be recorded in held_lwlocks[]. We'd have to duplicate a lot of code, or split LWLockRelease into multiple routines, neither of which seem attractive answers considering that this must be a can't-happen case anyway. PANIC it will be, unless someone thinks of a reason why not by tomorrow... regards, tom lane ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/docs/faq
