As a SaaS provider using postgresql schemas to separate clients we have a lot of tables, one set per customer schema. Some operations such as pg_dump, or schema migrations, takes locks on a lot of tables at once in the database, prior to dumping, or updating the database. For us this means that the default setting of 64 is too low and we'd like to be able to set the value ourself using parameters.

PostgreSQL on Azure is very outdated and extremely slow. It's very much unusable like this and we ended up moving to our own PostgreSQL container that don't have these issue. Please clarify that

https://github.com/cybertec-postgresql/pgsqueeze
pgsqueeze is an extension that removes unused space from a table and
optionally sorts tuples according to particular index (as if CLUSTER [2]
command was executed concurrently with regular reads / writes). In fact we try
to replace pg_repack [1] extension.

Users can decide when scheduled maintenance starts from in AWS.
e.g. Maintenance refers to the application of OS and database security patches.

Please be able to control schedule the maintenance in Azure Database for PostgreSQL from the users . It is problem that unexpected connection failures by maintenance in Azure Database.
For pre-planned maintenance, the convenience of users will be improved , if schedule the maintenance can be controlled.

Upgrading Data via Replication is documented as a method in the PostgreSQL docs.

When creating a read replica in the Azure Portal it is not possible to change the version (I assume it uses the same version as the master).

Please allow selecting a version when creating a replica so that this upgrade method would be possible.

Add prefix extension

PGroonga is a PostgreSQL extension to use Groonga as the index, and make PostgreSQL fast full text search platform for all languages (such as Japanese and Chinese).

It's a perfect fit together with timescaledb-extension if you have prometheus running in AKS

Please upgrade PostGIS 2.4 to PostGIS 2.5 on PostgreSQL 10. Several new features were introduced in PostGIS 2.5 which speeds up spatial calculations.

Provides a Foreign Data Wrapper for easy and efficient access to Oracle databases, including pushdown of WHERE conditions as well as comprehensive EXPLAIN and ANALYZE support.

PostGIS 3.0 is currently in alpha. It adds support for parallels processing of spatial queries which drastically increases the performance of spatial queries and makes PostGIS more inline with other advanced spatial databases. Please upgrade to this version of PostGIS when it is fully released.

Can the 'azurepgadmin' role be enhanced so that

ERROR: permission denied: "my-trigger-name" is a system trigger

is not encountered when executing

ALTER TABLE “my_table” DISABLE TRIGGER ALL

. The system trigger in question is one associated with a foreign key and the assocated triggers are system triggers.

RUM indexes are better suited for full-text search on PostgreSQL: https://akorotkov.github.io/blog/2018/05/21/fulltext-search-made-almost-right/.

It would be great to have the ip4r extension available in the Azure Database for PostgreSQL service. We already use this extension in our self-managed psql service to use IP addresses as native objects. It is very useful for some IPAM engines like nipapd, etc.

For more information about this extension: https://github.com/RhodiumToad/ip4r

Just wanted to upgrade the TimescaleDB extension from the current v1.1.1 to v1.3 or higher to be able to utilize the Continuous Aggregates feature.

Even though Azure DB for PostgreSQL provides secure connection, Applications on ARO needs to access Azure DB for PostgreSQL via internet.

Currently, VNET for ARO doesn't allow any modification, therefore, there is no option avoiding going through internet when applications connect to Azure DB for PostgreSQL.

There is no point in deploying a DB container on ARO. The user needs to consider how to manage DB.

If ARO allows modifying VNET creating Service endpoint for Azure DB for PostgreSQL, it could provide more secure route and low latency connections as well.

Azure team edit: I' creating this new idea on behalf of a customer to separate it from the votes for Citus on Azure Database for PostgreSQL. If you're interested in Citus columnar datastore (link below), please vote for this idea.
++++

I need this to do big-ish data things:

https://www.citusdata.com/blog/2014/04/03/columnar-store-for-analytics/

I am a huge fan of postgresql for data warehousing, and this is a key thing for having the ability to summary large tables quickly.

It'd be really useful to not have to rely on DB users for authentication but allow integration with AAD. That way we can enforce password complexity, expiry etc which can't be done with native users.
