A REINDEX INDEX done on a partitioned index builds a list of the indexes to work on before processing its partitions in individual transactions. When combined with a DROP of the partitioned index, there was a window where it was possible to see some unexpected "could not open relation with OID", synonym of relation lookup error. The code was robust enough to handle the case where the parent relation is missing, but not the case where an index would be gone missing. This is similar to1d65416661. Support for REINDEX on partitioned relations has been introduced ina6642b3ae0, so backpatch down to 14.
