Wondering What TODO

I’ve been thinking of adding a Kanban board to my site for a more advanced TODO list. So far I’ve looked at: Kanboard - Interesting and right now the main contender. It’s fast, easy to set up, and can use Postgres. It’s somewhat ugly, and the existing themes are few and far-between. It’s also PHP, which isn’t winning it any points. Also, every single theme breaks the code syntax highlighting in the hover tool-tip of the Board view.

PG Phriday: Community Edition

Postgres is one of those database engines that carves out a niche and garners adherents with various levels of religious zeal. The community, while relatively small when compared to that of something like MongoDB, is helpful almost to a fault. Members from the freshest minted newb to the most battle tested veteran will often trip over themselves to answer questions found in the various dedicated forums, mailing lists, and chat rooms.

PG Phriday: Who Died and Made You Boss?! (The Investigatining!)

The Postgres system catalog is a voluminous tome of intriguing metadata both obvious and stupendously esoteric. When inheriting a Postgres database infrastructure from another DBA, sometimes it falls upon us to dig into the writhing confines to derive a working knowledge of its lurking denizens. The trick is to do this before they burst forth and douse us with the database’s sticky innards and it experiences a horrible untimely demise.

PG Phriday: Design Pattern Workshop

Recently on the pgsql-performance mailing list, a question popped up regarding Postgres RAM usage. In this instance Pietro wondered why Postgres wasn’t using more RAM, and why his process was taking so long. There were a few insightful replies, and they’re each interesting for reasons that aren’t immediately obvious. Let’s see what is really going on here, and perhaps answer a question while we’re at it. Pietro presents several postgresql.conf settings, but here are the ones that matter:

PG Phriday: CONFLICT of Interests

MySQL has had a REPLACE INTO syntax to perform “UPSERT” logic since practically the very beginning. For the longest time, users who wanted to switch to Postgres, but for whatever reason relied on this functionality, were essentially trapped. Postgres 9.5 changed all that, but why did it take so long? As with much of Postgres history, it’s a long story. To really understand where Postgres started, we need to look at the “old” way of handling a row merge.
