Hi
one customer reported slow queries over information_schema.tables. There is
newer used a index over relname probably due casting to
information_schema.sql_identifier.
Slow query
select * from information_schema.tables where table_name = 'pg_class';
Usually, there is hard to fix it on application level due corporate
environment.
Regards
Pavel
