So, with all the prompts outlining the goals of the project, I’ve gone forward with the project, and step one is creating a PostgreSQL database on Azure.

First, on 9th of October 2025, Amit Kapila committed patch: Add "ALL SEQUENCES" support to publications. This patch adds support for the ALL SEQUENCES clause in publications, enabling synchronization/replication of all sequences that is useful for upgrades. Publications can now include all sequences via FOR ALL SEQUENCES. psql enhancements: \d shows publications for … Continue reading "Waiting for PostgreSQL 19 – Sequence synchronization in logical replication."| select * from depesz;
When using tsearch one usually, often, creates a tsvector column to put data in, and then create index on it. But, do you really need the index?

A significant shift has occurred in the data storage landscape over the last 10 years. Legacy environments saw data centers full of physical servers on racks, all taking up space in climate-controlled rooms with teams of database administrators overseeing operations 24x7.

Businesses are processing workloads as never before and cloud database management is what allows them to do this while scalin...| Paessler Blog (English)

A hash join is one of the most common join methods used by PostgreSQL and other relational databases. It works by building a hash table from the smaller input (called the build side) and then probing it with rows from the larger input (the probe side) to find matching join keys.Hash joins are especially efficient| Highgo Software Inc. - Enterprise PostgreSQL Solutions
On 20th of October 2025, Masahiko Sawada committed patch: Support COPY TO for partitioned tables.

Performance tests show … Continue reading "Waiting for PostgreSQL 19 – Support COPY TO for partitioned tables."| select * from depesz;

I wrote a blog post a couple of weeks ago entitled Is pg_dump a Backup Tool?. In that post, I argued in the affirmative, but also said that it's probably shouldn't be your primary backup mechanism. For that, you probably shouldn't directly use anything that is included in PostgreSQL itself, but rather a well-maintained third-party backup tool such as barman or pgbackrest. But today, I want to talk a little more about why I believe that pg_dump is both amazingly useful for solving all kinds of...| Robert Haas

Recently, I've been hearing a lot of experienced PostgreSQL users reiterate this line: "pg_dump is not a backup tool." In fact, the documentation has recently been updated to avoid saying that it is a backup tool, to widespread relief. Experienced PostgreSQL users and developers have been publicly called out for having the temerity to assert that pg_dump is, in fact, a backup tool. I find this narrative deeply frustrating, for two reasons.Read more »| Robert Haas

Hacking on PostgreSQL is really hard. I think a lot of people would agree with this statement, not all for the same reasons. Some might point to the character of discourse on the mailing list, others to the shortage of patch reviewers, and others still to the difficulty of getting the attention of a committer, or of feeling like a hostage to some committer's whimsy. All of these are problems, but today I want to focus on the purely technical aspect of the problem: the extreme difficulty of wr...| Robert Haas
