I am struggling to connect with pyCharm to a postgres instance running on amazon rds.
In host I plug in the Endpoint. I configure driver to be the jdbc jar file (external library).
Test connection says that the connection on port 5432 is refused: Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections.
On rds side:
For the security group I have an inboud rule for All traffic with source Anywhere
The VPC has DNS resolution and DNS hostnames enabled
VPC is publicly accessible
VPC classic link is enabled

I was using FDW extension in PostgreSQL from 2 years to load data from one database to another database. Now, one of my RDS has been moved from AWS to Azure. Now, when I tries to make connection from Azure to AWS it says the host is invalid. So, in this case FDW doesn't works if the RDS are from different service?

Actually i have to migrate the data from AWS RDS postgres to on premises postgres.
For this i have to establish connectivity between my AWS RDS db instance and on premises(ubuntu server).
I have already configured the inbound rules of security group in my RDS DB instance. But still i am not able to connect to AWS RDS db instance directly through my Ubuntu Machine..
Is there any issue with the firewall of my VM??
Error which i am getting:
psql: error: could not connect to server: Connection timed out
Is the server running on host "XXXXXX" (X.X.X.X/X) and accepting
TCP/IP connections on port 5432?
The database setting for publicly accessible is set to NO.
There are both public as well as private subnet associated with my RDS instance.
i have provided the type as postgreSQL , port 5432 , protocol TCP, source custom ip (X.X.X.X/32)
Any help will be much appreciated.
To access an Amazon RDS database from the Internet:
Set the database to Publicly Accessible = Yes (This resolves the DNS name to a Public IP address)
Put the database in a Public Subnet (Mixing public & private subnets in a Subnet Group is not advisable, because the results will be random! It will only be in one subnet at any time, but might change subnets when upgraded or failover is triggered.)
Add a Security Group that allows Inbound access on the appropriate port (PostgreSQL = 5432) from your IP address
Reference the database via its DNS Name shown in the Amazon RDS management console
Alternatively, keep the database in a Private Subnet and access via a VPN Connection or by Port Forwarding via a Bastion Server.
I have created an AWS RDS Instance with Postgres 10.6
I am trying to connect to it from my local system using below command:
psql --host=dev.xyz.ap-south-1.rds.amazonaws.com --port=5432 --user="postgres" --password --dbname=abc
The Inbound rules i have set are
Allow TCP traffic on 5432 from Anywhere.
Still I am getting below error:
psql: could not connect to server: Connection timed out
Is the server running on host "dev.xyz.ap-south-1.rds.amazonaws.com" (xxx.xxx.xxx.xxx) and accepting
TCP/IP connections on port 5432?
If Publicly accessible = No, then you will not be able to access the RDS database from outside the VPC.
This is because the DNS Name of the database will not resolve to an IP address.
I'm unable to connect to a new PostgreSQL in AWS RDS.
I have a Heroku app and I would like to use Amazon RDS for my database instead of Heroku. For that I've been following this guide: https://www.reinteractive.net/posts/128-heroku-app-backed-by-an-aws-rds-postgres-database
I've made a backup from my current Heroku DB and want to load it on the new database.
My security group for the database allows all inbound connections for port 5432 (0.0.0.0/0) and I've made a new VPC to have my DB set as Publicly Accesible (DNS hostnames and DNS resolution enabled). I created the database on postgres version 9.4.9.
However when I do:
-f latest.sql --host=xxx.xxx.us-west-2.rds.amazonaws.com --port=5432 --username=awsuser --password --dbname=mydatabase
from my computer, I only get a connection time out error:
psql: could not connect to server: Connection timed out
Is the server running on host xxx.xxx.us-west-2.rds.amazonaws.com" (1.2.3.4) and accepting
TCP/IP connections on port 5432?
The server is indeed running. In this case latest.sql is the backup I did. After this I edited the Database security groups to accept all connections (0.0.0.0/0) too.
Database Rules
(from what I've read this should not be necessary because I already have the VPC Security Group), but the result is the same.
Is there any way to trace what's going on / why is my connection getting blocked?
I have two machines in amazon. web01 and db01. I installed PostgreSQL on db01, and added the elastic ip of web01 to the pg_hba.conf
host dbname username 64.210.245.155/32 md5
and restarted the postgresql service. Now in web01 I tried to connect to the elastic ip of db01
$ psql -h 64.210.255.222 -U user -d database
psql: could not connect to server: No route to host
Is the server running on host "64.210.255.222" and accepting
TCP/IP connections on port 5432?
I also added the elastic ip of web01 to db01's security group for inbound traffic. What am I doing wrong and how can I get web01 to connect to pg on db01?
To start with, you want to be connecting to the internal IP. You can use the DNS name if your elastic IP as it will resolve to an internal IP within AWS instead of using the elastic IP directly.
Secondly, all public IPs are assigned via NAT. If your service tries to listen to that IP address it will fail. Generally the best thing to do is listen to all IPs, unless you are using VPC and have control of the internal IP.
Lastly, you will provide access to the web security group within the db security group. Even if two instances are in the same security group, they will not be able to access each other unless the group is given access to itself.
