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 wallevel needs to be set to logical and there needs to be an available output plugin. Unfortunately, PostgreSQL only comes with the testdecoding 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.…

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.

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.

pg_squeeze is an extension that removes unused space from a table and optionally sorts tuples according to particular index

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.24 votes -
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.

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.testparser is available on Amazon RDS

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

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

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…

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.

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.

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

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 pgterminatebackend(pgstatactivity.pid)
FROM pgstatactivity
WHERE pgstatactivity.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.
