Project mention: Ask HN: It's 2023, how do you choose between MySQL and Postgres? | news.ycombinator.com | 2023-05-11Friends don't let their friends choose Mysql :)
A super long time ago (decades) when I was using Oracle regularly I had to make a decision on which way to go. Although Mysql then had the mindshare I thought that Postgres was more similar to Oracle, more standards compliant, and more of a real enterprise type of DB. The rumor was also that Postgres was heavier than MySQL. Too many horror stories of lost data (MyIsam), bad transactions (MyIsam lacks transaction integrity), and the number of Mysql gotchas being a really long list influenced me.
In time I actually found out that I had underestimated one of the most important attributes of Postgres that was a huge strength over Mysql: the power of community. Because Postgres has a really superb community that can be found on Libera Chat and elsewhere, and they are very willing to help out, I think Postgres has a huge advantage over Mysql. RhodiumToad [Andrew Gierth] https://github.com/RhodiumToad & davidfetter [David Fetter] https://www.linkedin.com/in/davidfetter are incredibly helpful folks.
I don't know that Postgres' licensing made a huge difference or not but my perception is that there are a ton of 3rd party products based on Postgres but customized to specific DB needs because of the more liberalness of the PG license which is MIT/BSD derived https://www.postgresql.org/about/licence/
Some of the PG based 3rd party DBs:
Enterprise DB https://www.enterprisedb.com/ - general purpose PG with some variants
Greenplum https://greenplum.org/ - Data warehousing
Crunchydata https://www.crunchydata.com/products/hardened-postgres - high security Postgres for regulated environments
Citus https://www.citusdata.com - Distributed DB & Columnar
Timescale https://www.timescale.com/
Why Choose PG today?
If you want better ACID: Postgres
If you want more compliant SQL: Postgres
If you want more customizability to a variety of use-cases: Postgres using a variant
If you want the flexibility of using NOSQL at times: Postgres
If you want more product knowledge reusability for other backend products: Postgres
Project mention: Can I learn Python while practicing writing queries for SQL simultaneously? I've recently completed learning SQL and trying to get better at it. | /r/SQL | 2023-05-10You can practice both by using https://www.psycopg.org from your Python code to communicate with your database. When I wanted to practice some SQL, that's what I did (we use psycopg at work, so that's what I practiced with, making a dream journal thingy for myself that was better than just noting stuff in a notepad because I could then look up e.g. what other stuff was correlated with Y, how many times I dreamed of X, etc. etc.)
Project mention: Apache AGE: PostgreSQL Extension Graph Data Processing and Analytics | news.ycombinator.com | 2024-03-28
Thanks to MongoDB drivers all consistently providing connection monitoring and pooling functionality, external connection pooling solutions aren't required (ex: Pgpool, PgBouncer). This allows applications built using MongoDB drivers to be resilient and scalable out of the box, but based on what we understand regarding the number of connections applications establish to MongoDB clusters it stands to reason that at a certain point as our application deployments increase, so will our connections.
hey hn, supabase ceo here
we've been fans of Oriole for a while now and have been long-time supporters
in case you're jumping straight to the comments: OrioleDB is a table storage extension for Postgres. it acts as a drop-in replacement for the default postgres storage engine using the Table Access Method APIs (pluggable storage). the storage engine changes the representation of table data on disk. its architecture is designed to take advantage of modern hardware like SSDs and NVRAM. it implements MVCC, the feature that allows allows multiple connected users to see different versions of the data depending on when their transaction started, via an UNDO log rather than tuple versioning.
one caveat: it requires several patches to the postgres core to expand on the type of features external storage engines extensions can implement. for this reason it could be a while before you see this land as a default engine on supabase. we will probably make it available as an option for customers who want to experiment - no timeline is decided yet.
finally, we have been working with the team on decoupled storage and compute [0]. this is experimental but promising, especially with some recent advances in S3 (specifically Express One Zone [1]). we have a demonstration in the blog post.
i'll message Alexander in case there are any technical questions

Don't feel bad, lots of people get bitten by not reading all the way down to the bottom of their readme: https://github.com/hydradatabase/hydra/blob/v1.1.2/README.md... While Hydra may very well license their own code Apache 2, they ship the AGPLv3 columnar which to my very best IANAL understanding taints the whole stack and AGPLv3's everything all the way through https://github.com/hydradatabase/hydra/blob/v1.1.2/columnar/...
[Postgres Extensions] pg_cron 1.5.2 (new projects only) now supports sub-minute schedules. PR
pspg is a pager intended to be used with SQL command line clients. It was originally created for Postgres (hence the name), but also works with MySQL and others
https://github.com/okbob/pspg
This tutorial explains how to backup PostgreSQL database using pgBackRest and S3.
Project mention: Moving a Billion Postgres Rows on a $100 Budget | news.ycombinator.com | 2024-02-21Columnar store PostgreSQL extension exists, here are two but I think I’m missing at least another one:
https://github.com/citusdata/cstore_fdw
https://github.com/hydradatabase/hydra
You can also connect other stores using the foreign data wrappers, like parquet files stored on an object store, duckdb, clickhouse… though the joins aren’t optimised as PostgreSQL would do full scan on the external table when joining.
It works particularly well with pg_stat_statements[0] which tracks execution statistics of all SQL statements executed on your Postgres database.
It leans heavily on HypoPG[1], an excellent extension to determine if PostgreSQL will use a given index without spending resources to create them.

Project mention: Show HN: I built this Postgres logger for you guys to check out | news.ycombinator.com | 2023-08-24I think pgAudit it still the best and it's not a major issue. You can try my PR that fixes this issue https://github.com/pgaudit/pgaudit/pull/219 it should work and it should handle the other types of SELECT's that need update permissions but are not actually updating anything https://pglocks.org/?pglock=RowShareLock
If you want a tool that can ingest from a span port and generate netflow or IPFIX there is pmacct. This should work with your existing tooling that collects netflow data.
If you installed Postgres via Homebrew, you need to configure bundler so that when it installs the pg gem, it knows where to find the pg_config executable, which is installed as part of Postgres. The pg gem is the Ruby interface to Postgres and requires pg_config during installation. We can use this command to configure bundler so that it can find it and successfully install pg.
