![]() You may also have a look at the documentation describing pg_hba.conf structure here and how to configure PostgreSQL's incomming connections.Īnd - if you're super paranoid then you can change the IP in the pg_hba.conf every time you change your location/ip to connect to it. Local temporary table starts with, Global temporary table starts with 2. So - if you know the IP's (or ranges) from which you will be connecting then you can put them in `pg_hba.conf'. There are 2 types of temporary tables in SQL Server. However this poses some security risk due to exposing your DB to the internet and allowing connections from any IP. Now restart postgresql server (to be sure the changes will be taken into account) and try to connect $ psql -h your-postgres-server-ip -U user Next edit your pg_hba.conf file and add this at the end: host all all 0.0.0.0/0 md5 We see that the port 5432 is open for any IP's. Proto Recv-Q Send-Q Local Address Foreign Address State Now restart the service sudo service postgresql reload and check if your server accepts connections from all IP's: $ netstat -nlt ![]() You're able to SSH into your VM because it listens on a port 22 and accepts connections from avery IP:įor the moment it looks like you have a default configuration that allows only connections from localhost (127.0.0.1).įor the server to accept connections to your DB from every IP find a nf file and change a line from listen_addresses = 'localhost' to listen_addresses = '*'. You PostgreSQL database access is controlled by the pg_hba.conf you mentioned and nf files. Would I need to change it every time I change working location? There was a suggestion to edit the "pg_hba.conf". Or advice how to properly set the connection?

You can also customize the output using the configuration vars at the top of the file, but the defaults should work well for most people.I've installed Postgres on Google Compute engine. That's it! You now have access to exporting rows as batches. Create a new file called "SQL Batch Multi-Line " (The double extension is important for syntax highlighting).Additionally, in most cases, the difference in performance is very minor between batched inserts and 1 large insert. Allowing normal queries to run at the same time as the set of batched queries. Inserting in batches gives you a significant performance boost, while still preventing tables or rows from getting locked for too long. This is particularly harmful in production environments, especially when you need to comply with an SLA. Table & row locks block all other queries that modify data (causing a desync) and even some queries that read data (causing request lag). One large insert is technically faster than batched inserts however, this often comes at the cost of locking tables/rows for extended periods of time. This makes the individual inserts very slow, while batches avoid almost all of this overhead. In SQL, each query is parsed and executed separately which causes significant overhead between each query. In short, better performance and limited table/row locks when inserting thousands, millions, or even billions of rows.īatches perform orders of magnitude faster than individual inserts. I will also take a moment to say this is my first post and would love any feedback on improving it. While I could go on with my love/hate relationship with DG's features, (it's mostly love) it is fortunately easy enough to manually add some functionality. This isn't so much a "great new feature" as it is a missing feature from DataGrip.
