Ryan Booz: PGSQL Phriday #016
Invitation from Ryan Booz
Many of the PostgreSQL newbies that I’ve engaged with lately are coming from other databases often because of company priorities to start adopting Postgres and migrating projects. Inevitably, one of the first things they want to learn once data starts flowing is how to tune queries. They typically have a lot of experience doing this type of work previously, just not with Postgres.

Today I just wanted to step through getting QGIS connected to a Postgres database and the basic operations that let you connect the two systems.
Regina Obe: PostgreSQL Mistakes and How To Avoid them
The adoption of PostgreSQL is growing each year. Many people coming to PostgreSQL are often coming from other relational databases, with assumptions of how relational databases work. Although PostgreSQL may feel very familiar to these people, it is different enough to cause some misunderstandings which lead to bad and slow queries. There are also people coming often from only programming backgrounds, who assume data processing in SQL is much like data processing in any language.

Pavel Stehule: How fast is plpgsql?
Ten years ago I did some speed tests of plpgsql. I did same tests on same computer, and now, the plpgsql is about 3-4 times faster. There is still significant overhead against native (without plpgsql function) query, but it is reduced (little bit). I would to compare again with Python
