* docs: Fix broken or dead links Used the following commands to find broken links: 1. `lychee -E --dump https://freshrss.github.io/FreshRSS/en/ --include freshrss.github.io --output links.txt` 2. `lychee -v --suggest --archive wayback --timeout 5 -u "Mozilla/5.0 (X11; Linux x86_64; rv:148.0) Gecko/20100101 Firefox/148.0" --files-from links.txt --output output.txt` 3. `cat output.txt` Then did the same for https://freshrss.github.io/FreshRSS/fr/ We could look into using lychee in CI: https://github.com/lycheeverse/lychee?tab=readme-ov-file#github-action-usage * Replace PostgreSQL 16 link with current version Co-authored-by: Alexandre Alapetite <alexandre@alapetite.fr> * Remove paragraph about bug message format * Update README with official app website links * Replace broken French images with English versions * Fix broken Fever API docs link in French docs * Replace GNU Social link with new one in `shares.php` --------- Co-authored-by: Alexandre Alapetite <alexandre@alapetite.fr>

Database configuration
FreshRSS supports the databases SQLite (built-in), PostgreSQL, MariaDB / MySQL.
While the default installation should be fine for most cases, additional tuning can be made.
Full-text search optimisation in PostgreSQL
Without changing anything in FreshRSS’ code (which is using ILIKE), it is possible to make text searches much faster by adding some indexes in PostgreSQL 9.1+ (at the cost of more disc space and slower insertions):
CREATE EXTENSION pg_trgm;
CREATE INDEX gin_trgm_index_title ON freshrss_entry USING gin(title gin_trgm_ops);
CREATE INDEX gin_trgm_index_content ON freshrss_entry USING gin(content gin_trgm_ops);
CREATE STATISTICS freshrss_entry_stats ON title, content FROM freshrss_entry;
ANALYZE freshrss_entry;
Where freshrss_entry needs to be adapted to the name of the entry of a given use, e.g., freshrss_alice_entry.
Such an index on the entry.title column makes searches such as intitle:Hello much faster.
General searches such as Something search both on entry.title and entry.content and therefore require the two indexes shown above.
Likewise, if you wanted to speed up searches on the authors (author:Alice), you would add another index:
CREATE INDEX gin_trgm_index_author ON freshrss_entry USING gin(author gin_trgm_ops);
Etc. for other text fields. The list of fields can be seen in CREATE TABLE _entry section.
