Many argue which is better: PostgreSQL or MySQL. A recent post by MySQL evangelist and community manager Frederic Descamps prompted some criticism of the amount of time that it took for a particular bug to be fixed -- 14.5 years to be exact, from the initial report.

There’s a long list of technical and performance comparisons, but here’s the number one reason to choose Postgres over MySQL.

Community Drives Change …

One of the fantastic characteristics of Postgres leaders is their willingness to serve the community.

Yesterday I found out that one of our former team members, Devrim Gunduz, has created a new London PostgreSQL user group and they had their inaugural meeting in October. At the time of this writing there were 123 members in the group. This level of response shows a great demand for Postgres content. I spoke …

After much deliberation with the CMD community team we have launched the Denver Postgres User Group! We hope that our community in Denver, Boulder, and Colorado Springs will join us at upcoming events and submit content. It has been a long time since we have had an active Denver group and Denver is a hot bed for Postgres external development. Our first meeting will be announced soon and should …

Oracle 7.3 supports it!

That is how this all started. A gentleman tweeted about a Postgres limitation that Oracle has not had since at least since Oracle 7.3. 

The problem

As you can see in the tweet, Postgres by default will not defer a PRIMARY KEY check. Without the check being deferred the following will not work:

For most workloads the Postgres Autovacuum daemon works just fine. You go about your day with 3 workers that wake up once a minute to make sure that everything is nice and tidy. If things are dirty enough (around 10%) then one of the workers gets in gear and cleans things up. Unfortunately, if you have an inverted load from the norm, Autovacuum may not be able to keep up …
