In the past year, I have had many conversations with many clients and prospects about Postgres-BDR. For those of you who don’t know this Postgres-BDR has been in production for many mission critical deployments for quite some time. We have more clients coming on board each month. Most recently, I have been meeting with […]
I have written about managing a PostgreSQL commitfest before. During the PostgreSQL 13 development cycle, I did it again. This time I used a different strategy, mostly because I felt that there was excessive accumulation of very old patches that had received insufficient attention. So apart from bugfixes (which are always special cases), I focused […]
Now that PostgreSQL 12 is out, we consider foreign keys to be fully compatible with partitioned tables. You can have a partitioned table on either side of a foreign key constraint, and everything will work correctly. Why do I point this out? Two reasons: first, when partitioned tables were first introduced in PostgreSQL 10, they […]
I got tired of looking up regression_output/log/postmaster.log to find the PGSOCKET to use to connect to a running pg_regress‘s temp-install postgres so I wrote a little shell function for it. My patch to print a connst in pg_regress never got merged so I needed a workaround. I’m sure I’m not the only one, so here’s […]
Historically, PostgreSQL’s replication configuration has been managed via a configuration parameters stored in a dedicated configuration file, recovery.conf, which has been present in PostgreSQL since the introduction of archive recovery in PostgreSQL 8.0. One of the major changes in PostgreSQL 12, co-authored by 2ndQuadrant is the replacement of recovery.conf and the conversion of recovery.conf parameters […]

Release 11 of the PostgreSQL Buildfarm client is now available. The release includes numerous bug fixes plus following features: Allow a list of branches as positional arguments to run_branches.pl This overrides what is found in the config file. The list can’t include metabranches like ALL, nor can it contain regexes. improve diagnostic capture for git […]
With every new release of PostgreSQL, there are a range of performance enhancements. Some are system-wide and affect every user, but most are highly specific to a certain use case. In this post, I am going to briefly highlight three improvements in PG12 that speed up certain operations. 1. Minimal decompression of TOAST values TOAST […]
