pgstatindex failed with ERRCODE_DATA_CORRUPTED, of the "can't-happen" class XX. The other functions succeeded on an empty index; they might have malfunctioned if the failed index build left torn I/O or other complex state. Report an ERROR in statistics functions pgstatindex, pgstatginindex, pgstathashindex, and pgstattuple. Report DEBUG1 and skip all index I/O in maintenance functions brin_desummarize_range, brin_summarize_new_values, brin_summarize_range, and gin_clean_pending_list. Back-patch to v11 (all supported versions). Discussion: https://postgr.es/m/20231001195309.a3@google.com
