  1. Support for Ultra SSD SKU configuration

    For performance critical workloads and large volumes of data, storage access latency is critical. Please support a Ultra SSD SKU configuration.

  2. 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.

  3. 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

  4. 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.

  5. Ability to use PG FDW to access one PG server from another w/o opening the firewall to all of Azure

    I'd like a way to use Postgres foreign data wrapper (FDW) which is supported today to access one Azure DB for Postgres server from another, without opening the firewall on the first server to all of Azure.

  6. Ability to output data changes via logical decoding (ex. wal2json)

    PostgreSQL, since 9.4, has the ability to provide the list of changes made to a database in a manner that is transaction-safe and lossless.

    To enable this feature, the wal_level needs to be set to logical and there needs to be an available output plugin. Unfortunately, PostgreSQL only comes with the test_decoding plugin, which was only really meant as an example.

    AWS for example, has included wal2json support:

    https://aws.amazon.com/about-aws/whats-new/2017/07/amazon-rds-for-postgresql-supports-new-minor-versions-9-6-3-and-9-5-7-and-9-4-12-and-9-3-17/

    The simple wal2json output plugin would be a good way to provide access to this powerful feature for a wide audience.

    I'd also be fine with other output plugins. It may…

  7. 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…

  8. 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.

  9. Firewall option: Allow access from a specific Azure resource

    While the option to allow access to all Azure services is nice, I'd much rather be able to control what resources can reach my server on a more granular level.

    The vnet integration is excellent, but many Azure resources (I'm thinking specifically of Data Factory at the moment) aren't integrated with vnets, for various reasons.

  11. 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 …

  12. 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.

  13. Globally Unique/Custom Domain Names

    Procedurally generated uniqueness should be added to Domain Names to ensure that a namespace will remain available across Azure subscriptions. Users should not have to generate a globally unique server name. Something like “<server name>.<some hash>postgres.database.azure.com” where <some hash> is globally unique and provided by Azure.

  14. Need a way to terminate sessions to drop and recreate a database

    I have used the following script to kill connections prior to dropping, creating and loading a database on our in house postgresql instance:

    SELECT pg_terminate_backend(pg_stat_activity.pid)
    FROM pg_stat_activity
    WHERE pg_stat_activity.datname = 'TARGET_DB';

    But it requires superuser rights to kill the connections which is something we don't get on Azure.

    I would like some programmatic way to do this in Azure.

  15. Enable the ability to assign BYPASSRLS to PostgreSQL Roles

    It would be great to have the ability to assign BYPASSRLS to spefic users in the system so we could have a backup user who had access to all data data and could run pg_dump without errors and then all other users had row level security enabled to enforce the data people could see.

    This would provide an extra level of secuirty to the application as then even table owners would not be able to access all data where at present row level security is only enabled for standard users.

  16. allow to login with the real username instead of username@{server_name}

    our product running not only in Azure, but also in AWS and on-premises, the PostgreSQL on both of them don’t need to add ‘@{server_name}’ after the real username.

  18. Allow customization of space and IOPS for logs

    To allow for workloads that require verbose logging levels like DEBUG, it would be nice to be able to set (purchase) additional space or IOPS dedicated to storage of logs.
