Dirk,
May be you can use this
create view sesql_userindexes as
SELECT upper(c.relname) AS TBL_NAME, upper(i.relname) AS IDX_NAME,
CASE WHEN x.indisunique=false THEN 0 ELSE 1 END AS UNIQUE_FLAG, 1+
(CASE WHEN x.indkey[1]=0 THEN 0 ELSE 1 END)+(CASE WHEN x.indkey[2]=0 THEN 0 ELSE 1 END)+
(CASE WHEN x.indkey[3]=0 THEN 0 ELSE 1 END)+(CASE WHEN x.indkey[4]=0 THEN 0 ELSE 1 END)+
(CASE WHEN x.indkey[5]=0 THEN 0 ELSE 1 END)+(CASE WHEN x.indkey[6]=0 THEN 0 ELSE 1 END)+
(CASE WHEN x.indkey[7]=0 THEN 0 ELSE 1 END) AS IDXCOL_TOTAL, x.indkey AS COL_SEQ
FROM pg_index x, pg_class c, pg_class i
WHERE ((c.oid = x.indrelid) AND (i.oid = x.indexrelid))
and not (c.relname ~* 'pg_') ;
select * from sesql_userindexes order by tbl_name, idx_name ;
gives you detailed information about all user-defined indices.
