Yeah, maybe dblink and a LATERAL join might be an easy way. 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)
Thanks for the ideas. As I would want to keep it in the database, dblink
would be the way to go. Maybe, I will create a prodedure that creates a
view in the monitor schema accessing the respective databases with union
all to concatenate the data.
