t would be a good idea to have an SQL section where users can run optimization scripts like MYSQLTUNER etc and enter suggestioned changes in a GUI that directly change the mysql.conf directly and correctly.

An ability to monitor performance and tweak would be ideal, making the task of SQL performance monitoring and tweaking far easier.

Also optimize commands and other tasks could be run for this panel.

as well as optimize and the ability to add it to cron for weekly or monthly.

I'd be happy if you could integrate multiple MySQL Versions into Plesk. Each Customer should be able to choose his MySQL. Also choosing more than only one version should be implemented.

According to a ticket I just opened (80693) Plesk currently doesn't support a clustered MySQL server, e.g. an active/active Galera cluster.
To avoid data-loss or corruption in a server crash, I'd like to run MySQL in a Galera cluster to automatically sync the data again once Plesk's MySQL started after a crash.

I would like you to support PostgreSQL 10 on Onyx 17

phpPgAdmin support was dropped starting from Plesk Onyx 17.8
This means that Plesk does not have any management tool for Postgres databases shipped with it.

I suggest to include pgadmin in Plesk installation since the latest ve
rsion of this software (2018-09-06 - pgAdmin 4 v3.3 Released) has just been released, with adequate security. More info about it you can find here:
https://www.pgadmin.org/

The possibility to setup a replication for MySQL

Please do better integration of PostgreSQL into Plesk like CPU and memory usage in Health Monitoring and Dump button in Database page. Please also add PostgreSQL tuning into Plesk, especially for modern hardware with 32 or 64 GB memory and 4 to 8 cores and fast SSD or NVMe drives. Thanks!

Add the ability to create ODBC DNS for ODBC Driver 17 for SQL Server in Plesk.
Disabling TLS 1.0 breaks compatibility with earlier versions.

Currently Plesk does not support MySQL Governor feature https://docs.cloudlinux.com/index.html?mysql_governor.html
and mapping file /etc/container/dbuser-map has to be updated manually

Plesk already has integration with CageFS and LVM and detects it once those features installed on the server. It would be great if support for MySQL Governor be implemented in future.

Availability of reporting services on SQL server would be very useful on shared web hosting. My new ISP says Plesk doesn't support reporting services. I think it would be great if you did - not every site is a blog or simple brochure style. Any small scale business site still requires reporting, and SSRS is a natural fit for ASP.Net hosting.

Please add a simple button that retrieve my actual public IP and inserts it in the "Allow remote connections from" text area.
The page is the database user edit (or creation).

Many a times during database updates / ddl script executions the log file of MSSQL database becomes too large. There should be an option to shrink the log files. Currently this feature is disabled for both SQL Server Management Studio and Query.

Currently, when the database is copied the notification is sent to subscription owner.
It would be good to add functionality to disable such notifications or change the recipient mail address.

Implement the Contained Databases MS SQL feature in order to limit the database users ability to see MS SQL database names which are not owned by him.

adding most common plugins (like network) to sw-collectd to send data to central collectd server->influxdb and process with grafana

Possibility to change mysql data path keeping it on the new location when plesk updates.

Today when plesk update and a new version of mysql come with it, mysql databases stop working.

PostageSQL provides some powerful function to process non-relational data (eg: "jsonb") after version 9.4.
Would you please upgrade that?
Thanks.

Please add functionality to assign an already existing database from a remote database server to a domain.

For example, set a MySQL database on one server but connect it to my website on the Plesk.
