When I first saw the option of create DBs, I thought it was something like I'm suggesting. MongoDB, MariaDB, CouchDB, etc, etc. This will be super cool. :)

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.

Doing this by hand is very time consuming. An option for rename database would be great feature.

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.

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/

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 to see support for the upcoming MySQL 8.
Currently there is no support inside plesk and using a possible workaround with docker isn't possible out of the box.

MySQL Community Server 8.0.4 is already a Release Candidate.

The possibility to setup a replication for MySQL

add mssql support and management in linux plesk edition on virtual machine just like now support mysql

Right now "Website copying" feature does not copy database(s) that related to the website that will be copied.

It would be great if Plesk will suggest to copy the website's database(s) if there are any.

It is understood that in general such feature can not guarantee that copied website will work with the copied database. However it will simplify web developer's work.

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.

Plesk repair db should fix issue "Integrity constraint violation: 1062 Duplicate entry for key 'PRIMARY'"
https://support.plesk.com/hc/en-us/articles/115003292185-Unable-to-create-object-in-Plesk-SQLSTATE-23000-Integrity-constraint-violation-1062-Duplicate-entry-for-key-PRIMARY-

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 even if MariaDB is installed on the server, in Plesk > Tools&Settings > Database servers it is written as MySQL It would be nice to show actual database type .

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.

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.

I just installed myLittleAdmin into several of our Plesk servers only to find out that each customer on the server would need to create a new DNS record for mssql.domain.com for it to work. I also found that if the client's site is not secured with an SSL cert, myLittleAdmin won't be secured either. I suggest that myLittleAdmin be updated so that it uses the base URL of the server, which is SSL secured. Or at the very least, identify how to secure access to myLittleAdmin via the server's SSL cert even if the customer's site isn't secured.
