PostgreSQL does not use IN-PLACE update mechanism, so as per the way DELETE and UPDATE command is designed,

Puppet is open source software for configuration management and deployment. Founded in 2005, it’s multi-platform and even has its own declarative language for configuration.
A global index, by very definition, is a single index on the parent table that maps to many underlying table partitions. The parent table itself does not have a single, unified underlying store so it must, therefore, retrieve the data satisfying index constraints from physically distributed tables. In very crude terms, the global index accumulates data in one place so that data spanning across multiple partitions are accessed in one go as opposed to individually querying each partition.
Many PostgreSQL database users might have stumbled over the effective_cache_size parameter in postgresql.conf. But how can it be used to effectively tune the database and how can we speed up PostgreSQL using effective_cache_size? This blog will hopefully answer some of my readers’ questions and reveal the hidden power of this secretive setting.
a) you can use litecli. litecli is able to use pspg
b) generate CSV from sqlite client - this format is well readable for pspg
sqlite3 -csv -header testdb.db 'select * from foo2' | pspg --csv --csv-header=on --double-header
Thank you for tip to Trent W. Buck.
OK, first, “OGR” is a subcomponent of the GDAL toolkit that allows generic access to dozens of different geospatial file formats. The OGR part handles the “vector” data (points, lines and polygons) and the GDAL part handles the “raster” data (imagery, elevation grids).

If you have something interesting to day about PostgreSQL, we [would love to get a proposal from you]. Even if you have never spoken before, consider responding to the CfP! PgDay 2020 is particularly friendly to first-time and inexperienced speakers. You’re among friends! If you use PostgreSQL, you almost certainly have opinions and experiences that others would love to hear about… go for it!
The very first PgDay San Francisco is coming to the Swedish-American Hall on January 21, 2020. It’s going to be an amazing event.If you have something to say about PostgreSQL…
… the Call for Proposals is now open through November 22, 2019. We are looking for 40 minute talks about anything related to PostgreSQL. First-time speakers are particularly encouraged to send in proposals.
I’ve been at dinners before with developers that admitted developers, themselves included, can be a bit opinionated. In one case one said for example, “I love Postgres, but I have no idea why.” They were sitting at the wrong table to use Postgres as an example… But it is quite often that I am asked Why Postgres.
The call for sponsors for pgDay Paris 2020 is now open. There are two levels available: Partner and Supporter. The Partner level, which gives you a booth at the event, is limited to just five spots so hurry up and get yours now before it's too late!
Ever wondered how to import OSM (OpenStreetMap) data into PostGIS  for the purpose of visualization and further analytics? Here are the basic steps to do so.
There are a bunch of tools on the market— osm2pgsql; imposm; ogr2org; just to mention some of those. In this article I will focus on osm2pgsql  .

One of the things that makes managing geospatial data challenging is the huge variety of scales that geospatial data covers: areas as large as a continent or as small as a man-hole cover.
The data in the database also covers a wide range, from single points, to polygons described with thousands of vertices. And size matters! A large object takes more time to retrieve from storage, and more time to run calculations on.
