Check syscache result in AlterStatistics The syscache lookup may return NULL even for valid OID, for example due to a concurrent DROP STATISTICS, so a HeapTupleIsValid is necessary. Without it, it may fail with a segfault. Reported by Alexander Lakhin, patch by me. Backpatch to 13, where ALTER STATISTICS ... SET STATISTICS was introduced.
