Jira Link: DB-5099
After creation tables like this it is not possible to reconnect to DB
CREATE TABLE t_with_cast (d DATE, v INT) PARTITION BY RANGE(EXTRACT(month FROM d));
CREATE TABLE t_with_cast_p0 PARTITION OF t_with_cast FOR VALUES FROM (1) TO (12);
The reason is that tables uses functions for partitioning and some of them requires implicit casts. As a result pg_cast table is accessed but it is not prefetched.
