Something like: create extension dblink; select d.datname,c.relname from pg_database d, lateral (select * from dblink('dbname='||d.datname,$$select relname from pg_class where relname = 'pg_class';$$) c(relname text)) c (relname) where d.datallowconn; datname | relname ------------+---------- postgres | pg_class template1 | pg_class regression | pg_class (3 rows) David
