   I was able to reproduce connections growing with jdbc postgresql catalog, on refresh+select cycle.
   ```sql
   refresh catalog pg_jdbc_app;
   select * from pg_jdbc_app.public.data limit 20;
   ```
   From looking at source code, it seems, that [setUninitialized](https://github.com/apache/doris/blob/master/fe/fe-core/src/main/java/org/apache/doris/datasource/ExternalCatalog.java#L290) doesn't trigger onClose, and onClose is [used by JdbcExternalCatalog](https://github.com/apache/doris/blob/master/fe/fe-core/src/main/java/org/apache/doris/datasource/jdbc/JdbcExternalCatalog.java#L74) to release connections. So after refresh a new jdbc client is created with a new connection, increasing the count
