Pg_stats_actvity is used in pgadmin 4 but it give only current queries.
And also checked on azure portal for logs in server logs there can't see the logs for queries.
If anyone know help on this it is azure postgresql server.
Need Queries for one perticular database.
I tried below query in pgadmin 4
Select * from pg_stats_activity
It is azure postgresql single server i checked logs and diagnostics.
Also tried explain analyse.
Help me to get list of queries in postgresql database for perticular time interval
You have several options in Postgres to capture queries.
You've already found that pg_stats_activity shows active, running queries.
The pg_stat_statements extension will show aggregated information for query fingerprints.
The log_statement configuration will log queries that were sent to the database into your postgres.log. Use the log_line_prefix configuration to capture more details into the logs.
The pgaudit extension will capture queries that were executed on the database, with nicely formatted output for easy parsing or to send to log aggregation tools.
Here's an Azure doc that describes how to set these in the UI and how to view the resulting logs: https://learn.microsoft.com/en-us/azure/postgresql/single-server/concepts-server-logs.
In your case, setting log_statement to 'all' should be a good start.

I'm using the Postgres database from AWS RDS. I want to see the full text of Top query in AWS RDS performance insights.

As per the documentation, I've updated the track_activity_query_size to the max: 102400, have also tried rebooting the Postgres DB instance, still, it shows the same truncated <= 500 chars.
PS: my Postgres DB instance version is 12.5
Can someone help?
You can enable the PostgresSQL logs and search the half length queries in the latest logs wherein you will get the full length queries of the same.
Go to the "Logs & events" tab in the respective database from RDS console and download the log. Then search using some file editor to get the full length queries.
I am using Postgres in RDS instance. I have enabled log_connections and log_disconnections parameter and also setup pg_audit extension to capture changes for DDL. I would like to know that is there any SQL query for looking at the logs of session login and logout and pg_audit DDL changes for any date. Manually looking at log file every time becomes much tedious.
Till date, I couldn't find any alternative apart from looking at logs file.
There is a postgres 9 with database AAA that is used by my application. I use pgadmin 4 to manage it manually.
I would like to check what queries are executed by this application on database AAA in real time.
I did a research about monitoring options in pgadmin in vain.
Is is possible to do that by using just pgadmin4? Or is it necessary to use another tool (if yes - what is he name of this tool)?
When I point pgAdmin4 at a 9.6 server, I see a dashboard by default which shows every session (done by querying pg_stat_activity). You can then drill down in a session to see the query. If a query last for less time than the monitoring interval, then you might not see it if the sample is taken at the wrong time.
If that isn't acceptable, then you should probably use a logging solution (like log_statemnt='all') or maybe the pg_stat_statements extension, rather than sample-based monitoring. pg_stat_statements doesn't integrate with the dashboard in pgAdmin4, but you can select from the view from an SQL window just like you can run any other SQL. I don't believe pgAdmin4 offers a built-in way to monitor the database server's log files, the way pgAdmin3 did.
I've recently joined a company with a mixed set of databases that include a Redshift cluster and some SQL databases. I'd like to use a single IDE to access both for analytical reporting, so I don't have to switch between tools. I'm currently using workbench, which works, but it's not clicking with me.
I do like Azure Data Studio, but it's SQL Server and Postgres only. Given the similarities between Redshift and Postgres, I thought I'd see if I could connect using the Postgres driver.
I've installed the Postgres extension and can "connect" to the database. However when I try to explore the database using the tree view, I get the error message 'Cannot Expand Node'. When I run a simple query that works in workbench, e.g.
Select * from [server].[database].[table]
I get the following Error message:
Started executing query at Line 1
cursors can only be used within the transaction that created them.
Total execution time: 00:00:00.019
I know I'm trying to do something that shouldn't be done. And if I can't, I can't. But has anyone here managed to get a redshift connection going in Azure Data Studio?
FWIW, I've come across a GitHub Repository that may be a Redshift driver for data studio - but this looks like a clone of the Postgres driver, with no activity since march (not even renaming the 'Postgres' titles to Redshift)... and therefore I'm dubious.
When trying to connect to my Amazon PostgreSQL DB, I get the above error. With pgAdmin, I get "error saving properties".
I don't see why to connect to a server, I would do any write actions?
There are several reasons why you can get this error:
The PostgreSQL cluster is in recovery (or is a streaming replication standby). You can find out if that is the case by running
SELECT pg_is_in_recovery();
The parameter default_transaction_read_only is set to on. Diagnose with
SHOW default_transaction_read_only;
The current transaction has been started with
START TRANSACTION READ ONLY;
You can find out if that is the case using the undocumented parameter
SHOW transaction_read_only;
If you understand that, but still wonder why you are getting this error, since you are not aware that you attempted any data modifications, it would mean that the application that you use to connect tries to modify something (but pgAdmin shouldn't do that).
In that case, look into the log file to find out what statement causes the error.
This was a bug which is now fixed, Fix will be available in next release.
