Ah, bueno, no es lo mismo. Prueba así:
SELECT ts.*, pg_relation_size(ts.relid) AS table_size,
pg_total_relation_size(ts.relid) AS total_size,
ios.heap_blks_read, ios.heap_blks_hit, ios.idx_blks_read,
ios.idx_blks_hit,
ios.toast_blks_read, ios.toast_blks_hit, ios.tidx_blks_read,
ios.tidx_blks_hit
FROM pg_stat_user_tables ts LEFT JOIN pg_statio_user_tables ios on
ts.relid = ios.relid
WHERE ts.relname = $1
