Make activity search properly use GIN indexes
The original approach to search in GIN indexes is to use
`to_tsvector(text)` in the WHERE clause of the query. According to
postgres docs [pdoc], this method does not make use of the index,
while `to_tsvector(config, text)` does. This commit changed the
query to use the two-argument `to_tsvector()`.

[pdoc]: https://www.postgresql.org/docs/12/textsearch-tables.html

To obtain the search config in use, we make a query to the db first.
The `::regconfig::oid` hack is needed because Postgrex does not support
regconfig type directly [postgrexbug]. I use the conversion from and to
`oid` instead of `text` because I tested in the actual DB and querying
using the conversion via `text` is slow just as the one-argument
`to_tsvector()` variant.

About

Pleroma is a microblogging server software that can federate (= exchange messages with) other servers that support ActivityPub. What that means is that you can host a server for yourself or your friends and stay in control of your online identity, but still exchange messages with people on larger servers. Pleroma will federate with all servers that implement ActivityPub, like Friendica, GNU Social, Hubzilla, Mastodon, Misskey, Peertube, and Pixelfed.

Pleroma is written in Elixir and uses PostgresSQL for data storage. It's efficient enough to be ran on low-power devices like Raspberry Pi (though we wouldn't recommend storing the database on the internal SD card ;) but can scale well when ran on more powerful hardware (albeit only single-node for now).

For clients it supports the Mastodon client API with Pleroma extensions (see the API section on https://docs-develop.pleroma.social).

Installation

If you are running Linux (glibc or musl) on x86/arm, the recommended way to install Pleroma is by using OTP releases. OTP releases are as close as you can get to binary releases with Erlang/Elixir. The release is self-contained, and provides everything needed to boot it. The installation instructions are available here.

From Source

If your platform is not supported, or you just want to be able to edit the source code easily, you may install Pleroma from source.

OS/Distro packages

Currently Pleroma is not packaged by any OS/Distros, but if you want to package it for one, we can guide you through the process on our community channels. If you want to change default options in your Pleroma package, please discuss it with us first.

Docker

While we dont provide docker files, other people have written very good ones. Take a look at https://github.com/angristan/docker-pleroma or https://glitch.sh/sn0w/pleroma-docker.

Raspberry Pi

Community maintained Raspberry Pi image that you can flash and run Pleroma on your Raspberry Pi. Available here https://github.com/guysoft/PleromaPi.

Compilation Troubleshooting

If you ever encounter compilation issues during the updating of Pleroma, you can try these commands and see if they fix things:

  • mix deps.clean --all
  • mix local.rebar
  • mix local.hex
  • rm -r _build

If you are not developing Pleroma, it is better to use the OTP release, which comes with everything precompiled.
