Thoughts on Uber’s List of Postgres Limitations

August 2, 2016/8 Comments/in 2ndQuadrant, Simon's PlanetPostgreSQL /by Simon Riggs

An Uber technical blog of July 2016 described the perception of “many Postgres limitations”. Regrettably, a number of important technical points are either not correct or not wholly correct because they overlook many optimizations in PostgreSQL that were added specifically to address the cases discussed. In most cases, those limitations were actually true in the […]

Failover slots for PostgreSQL

Logical decoding and logical replication is getting more attention in the PostgreSQL world. This means we need it working well alongside production HA systems – and it turns out there’s a problem there. Replication slots are not themselves synced to physical replicas so you can’t continue to use a slot after a master failure results […]

On pglogical performance

January 8, 2016/1 Comment/in pglogical, PostgreSQL, Tomas' PlanetPostgreSQL /by Tomas Vondra
