And what happens if you run this query?
SELECT idstat.schemaname AS schema,
idstat.relname AS table_name,
indexrelname AS index_name,
idstat.idx_scan AS times_used,
pg_size_pretty(pg_relation_size(quote_ident(idstat.schemaname) || '.' || quote_ident(idstat.relname))) AS table_size,
pg_size_pretty(pg_relation_size(quote_ident(idstat.schemaname) || '.' || quote_ident(indexrelname))) AS index_size,
n_tup_upd + n_tup_ins + n_tup_del as num_writes,
indexdef AS definition
FROM pg_stat_user_indexes AS idstat
JOIN pg_indexes ON indexrelname = indexname
JOIN pg_stat_user_tables AS tabstat ON idstat.relname = tabstat.relname
WHERE indexrelname = ' {YOUR QUERY NAME } ';
Sorry.. not sure what I should put into the WHERE clause ..
But, taking off the WHERE it returns me 600 rows
