(Cross-region) Read replicas
Would be great to have an ability to have a master in one region (e.g. Central US) and read-only replicas in other regions (e.g. West/East US)
(renamed; merged with "active geo-replication")

Cross region read replicas are now in public preview for Azure Database for PostgreSQL.
You can create cross region replicas via the Azure portal. Learn more here: https://docs.microsoft.com/azure/postgresql/howto-read-replicas-portal
Thank you for your support of this feature.

Add ability to authenticate against Azure Active Directory
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.

Logical Replication
I have a pretty large database, over 70GB, and cannot afford to have downtime with a full backup and restore. Please add support for logical replication with pg logical, slony, or another means.

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:
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…

Need test_parser extension
We are using tsvector for full text search.
And we want to use test_parser extension.Although test_parser's doc says "It doesn't do anything especially useful".
It is actually very useful when using custom tokenizer.test_parser is available on Amazon RDS

Ability to scale between different tiers
Right now, it doesn't seem to be possible to scale from Basic to Standard. Would be good if that was possible.

Today we support migration between General Purpose and Memory Optimised tiers. We don’t have an automated migration between either of those tiers and the Basic tier.
Please share in the comments whether you need a migration between Basic and GP/MO, and do add details on why.

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

pgagent extension
We need to run regular maintenance tasks on our database, which we usually perform with pgagent https://www.pgadmin.org/docs/pgadmin3/1.22/pgagent.html
Pgagent will be installed as a service on the application server, but for pgagent to work we need the pgagent extension deployed in the application database, see also https://www.pgadmin.org/docs/pgadmin3/1.22/pgagent-install.html#database-setup

Azure Powershell SDK support for PostgreSQL
There are great ways to manage the PostgreSQL in Azure via the Azure CLI. https://docs.microsoft.com/en-us/azure/postgresql/sample-scripts-azure-cli.
It would be great to get this possibility as well in Powershell

Support stored procedures in Python
I would like Azure to be the first cloud service to support the Pl/Pythonu extension. There are security risks involved with supporting this extension, so innovation will be needed, but I believe there is a huge machine learning community that would enjoy it if they could run Python code close to their data.

Configurable autovacuum
Our database is in use, in reading and writing, 24 hours per day through batch elaborations and online transactional operations. In our scenario, the auto vacuum is dangerous because it can slow down operations in the wrong moment of the day causing low answer times or even unavailability of our web application.
For this reason, we decided to turn off the auto vacuum and manage manually the maintenance routine of our tables: we use pgagent to schedule daily vacuum analyze of our tables and manually run vacuum full on large tables when needed (eg. their size on disk is too…

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.

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.
