| Allow plan cache result type to revalidate on the fly Usually, when a relation gets changed by a DB user, an invalidation message is sent to the shared context. Plancache will revalidate this behavior multiple times during the execution so that if the base relation changes, the cached plan will be updated accordingly. However, Postgres does not allow the resulting attributes to change because changing the query's result on the fly requires extra hand- ling on the user application, which is out of the DB kernel's control. Also, it will generate unwanted behavior in a concurrent transactional application. Due to the user's heavy request, we are allowing this in this patch and introduced a new POSTMASTER GUC to control this behavior. This GUC is a POSTMASTER type because the result-checking behavior is a flag (i.e., an intrinsic attribute) of the plan cache, initially only for transactional statements. We need to ensure that when the user changes the GUC, no plan cache is working at the time. | 2 年前 |
