What should I disable? Corrupt index sounds like a possible case, but
how do I fix this?
EXPLAIN ANALYZE
select * from cubesocialnetwork.tmp_autenticazionesocial where
idautenticazionesocial = 1622
"Index Scan using tmpautenticazione on tmp_autenticazionesocial
(cost=0.00..8.27 rows=1 width=530) (actual time=0.078..0.081 rows=1
loops=1)"
" Index Cond: (idautenticazionesocial = 1622)"
"Total runtime: 0.128 ms"
