simple query running for ever

I wrote a simple query, and it is taking too long, not sure what is wrong in it, even its not giving EXPLAIN ANALYZE.

select T0."physical_address_sid", T0."individual_entity_proxy_id", T2."infrrd_hh_rank_nbr"
from "cms_prospects".PROSPECT T0
--inner join "sas_prs_tmp".DEDUPE3583E3F18 T1 on T0."individual_entity_proxy_id" = T1."individual_entity_proxy_id"
left join "cms_prospects".INDIVIDUAL_DEMOGRAPHIC T2 on T0."individual_entity_proxy_id" = T2."individual_entity_proxy_id"

"Merge Left Join (cost=55.96..18147747.08 rows=213620928 width=20)"
" Merge Cond: (t0.individual_entity_proxy_id = t2.individual_entity_proxy_id)"
" -> Index Scan using pk_prospect on prospect t0 (cost=0.57..10831606.89 rows=213620928 width=16)"
" -> Index Only Scan using indxp_individual_demo_infrrd_hh_rank_nbr on individual_demographic t2 (cost=0.57..5013756.93 rows=260652064 width=12)"

Any suggestions or help would be highly appreciated.

Best regards,
