create or replace view dba.all_indices_types as
    select tbcl.relnamespace::regnamespace::text||'.'||tbcl.relname as
table_name
            , ndcl.relname as index_name
            , array_agg(ty.typname order by att.attnum) as index_types

    group by tbcl.relnamespace::regnamespace::text||'.'||tbcl.relname
            , ndcl.relname
    order by 1, 2;
select * from dba.all_indices_types where index_types &&
'{"text","varchar","char"}';

(This view might not handle indices on the parents of declared-partition
