Siguio sin andar pero siguiendo tu indicacion tambien castee la otra
expresion y anduvo :D

indexrelname::regclass

quedo asi ( y anda, no da error. )
SELECT idstat.relname AS table_name,
indexrelname AS index_name,
idstat.idx_scan AS times_used,
pg_size_pretty(pg_relation_size(idstat.relname::regclass )) AS
table_size, pg_size_pretty(pg_relation_size(indexrelname::regclass))
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 idstat.idx_scan < 200
AND indexdef !~* 'unique'
ORDER BY idstat.relname, indexrelname;
