  1. Resource Governace for CPU and Memory

    We are running a multi-tenant system leveraging Azure PostgreSQL.
    During heavy load, one Tenant can impact the system to a point where other databases are effected.

    Wondering if you are planning to support some type of resource governance in the future similar to Azure SQL
    https://docs.microsoft.com/en-us/sql/relational-databases/resource-governor/resource-governor-resource-pool?view=sql-server-2017

    I realize it wont be the same implementation, but maybe a new connectionstring parameter that could be set to limit CPU/Memory could be a start?

  2. Add support for auto_explain to collect access plans of the slow queries

    auto_expalin would help us collect access plans of the queries which exceed a threshold of the query execution time.

  3. Reader Role can view Query Text


    On AZ PostgeSQL Performance Insight, the role of Reader can view everything but not “query text”,
    so basically like most of things in Azure we believe that Reader role should also be able to
    view query text. And that is the issue and needs to be fixed in future releases.

  4. Ability to restore data from a snapshot

    We have a transient workload that only needs to run once every week at most. However, the DB state needs to be saved at the end of each run. Since the workload only runs occasionally, it costs quite a lot to keep the server running in the meanwhile, even at the minimum size for the tier.

    While it is possible to pg_dump/restore the data, this is very slow compared to restoring from a snapshot, which would be nearly instantaneous. Currently, deleting a server also removes the ability to access backups for the server.

    If one could optionally save a snapshot…

  5. Azure VNet in paired region

    For Azure SQL, service endpoint should allow traffic not only within a virtual network's region but also extend to include the paired region where the virtual network is deployed.

    (Idea submitted by Manish Kumar from the engineering group of Azure Database for PostgreSQL/MySQL service on behalf of one of our customers and in order to elicit feedback from other customers and users).

  6. Rename server

    Gaging interest for being able to rename a server/instance.

    For instance some customers shared that the naming convention they use for servers changes as a server moves from one stage of its lifecycle to another (test -> staging -> prod for instance)

  7. Provide actual memory being used (in GB) in Azure Monitor

    Provide actual memory being used (in GB) in Azure Monitor in addition to % memory used. The customer scenario is for the Persona of a QA/Test professional. Actual memory used is much more useful than % used as it related to determining the quality of a product / service. % used is tailored to SRE/Ops persona.

  9. Server-side connection pooling

    Would be great if it was possible to enable server-side connection pooling (e.g. Pgpool-II or PgBouncer) right from the portal.

  10. Native Python and R support - extensions plpythonu, plpython2u, plpython3u

    Please support extensions plpythonu, plpython2u, plpython3u so functions etc. can have Python code.

    Similar request for R support with extensions like PL/R

  11. Support for Ultra SSD SKU configuration

  12. effective_cache_size

    You should allow tuning of memory-related parameters. I have a 15GB server and the effective_cache_size is 1536MB; it should be eight times as high. Without tuning these parameters my application is simply too slow to run on your environment.

  13. Better support for automation of installation in ARM Template / PowerShell

    We massively deploy PostgreSQL instances. We (for exemple) need to automatically deploy configuration (for instances log_* parameters). It's possible to modify configuration with AZ commands. The other automation tools don't have the required functionality:

    * ARM Template cannot deploy instances with a set configuration.

    * Python2 should provide the necessary tools via azure.mgmt.* but is not very well documented (it's still in preview)

    * PowerShell as no options for that. (and very few means to interact with Postgres in general).

    In general, the support for postgres is bad in automation tools (and the feature coverage not uniform). We have to…

  14. pgTAP support for application testing

    We are working on migrating our app to Azure, and our app has unit/regression tests with using pgTAP [1].

    I would like Azure PostgreSQL to support pgTAP to allow us for application compatibility test.

  16. BYOK Encryption Key

    For governance reasons for managing PHI, we need to BYOK for the Disk Level Encryption. Is there any plan to expose the ability to have the storage account that the underlining managed system is using to a key that's stored in key vault?

    We can't host our postgresSql Database in Azure's managed solutions, until we can.

  17. Enable shutdown (deallocate equivalent) for Postgres when not in use.

    For non-production environments it would be a helpful cost saving feature to be able to 'turn off' / deallocate Azure Databases (of all types not just postgres) when they are not in use.

    While the prevailing logic would suggest that non-production environments should be destroyed when not in use, this is sometimes not convenient or practical when environments are required on (relatively) short notice and DB content sizes are relatively large

  18. Making checkpoint_timeout longer to prevent freqent checkpointing

    We are planning our PostgreSQL database to move to Azure Database for PostgreSQL.

    Now, we are working on performance analysis and tuning (for database refactoring) prior to moving to Azure, and we have found that frequent checkpoints are generating heavy load.

    So, we have checked the checkpoint parameters on Azure, and we afraid of that checkpoint_timeout (5min) is too short and it couldn't be changed by the user. It could generates frequent checkpoints.

    I think 30~60min for the checkpoint_timeout parameter is very common [1], so I hope Azure would have that as the default value.

    [1] Basics of Tuning Checkpoints …

  19. Enable the Pgstattuple Extension

    The extension pgstattuple is best used when you suspect something is amiss with the performance of a query and you suspect bloat.

    The pgstattuple is the most accurate way to determine the bloat in a particular table or index.

    I would like the ability to run the command manually as part of my debugging exercises.

    It is not required that pgstattuple be run as a service because it is intrusive.
