We analyzed it and determined the best course of action was to add an index. PostgreSQL disagreed, and outrightly refused to employ the index. Following is the story of the negotiation that took place to push past the blatant rejection of Postgres.

You might have heard “it’s important to know your data” when working with databases. But what does that look like in practice? This post is one answer: an example of how knowing our data helped us debug a slow query.

Mattermost query Postgres data then index into ElasticSearch for search, but they discovered a slow query. The walk us through the investigation process and run EXPLAIN to debug the slowness.

In this post, let’s see how to control psql from outside with the coproc functionality in bash.
