Plugins/af_psql_trgm/init.php:263 array_search() expects parameter 2 to be array, boolean given

After enabling of af_psql_trgm plugin, I do have errors in log (probably during refresh), which I can’t figure out.

E_WARNING (2)	plugins/af_psql_trgm/init.php:263 array_search() expects parameter 2 to be array, boolean given

1. plugins/af_psql_trgm/init.php(263): array_search(5, )
2. classes/rssutils.php(745): hook_article_filter(Array)
3. classes/rssutils.php(192): update_rss_feed(5, 1, )
4. update.php(197): update_daemon_common(50)

The problematic code

261                 if (!$enable_globally) {
262                         $enabled_feeds = $this->host->get($this, "enabled_feeds");
263                         $key = array_search($article["feed"]["id"], $enabled_feeds);
264                         if ($key === FALSE) return $article;
265                 }

it seems like a minor bug caused by uninitialized plugin data, try enabling the plugin for at least one feed (or maybe even saving plugin preferences once is enough) and see if it helps.

well, this points me to something. I have not enabled PostgreSQL extension correctly on first try (didn’t apply on tt-rss separate DB, but to root one only) and then I didn’t re-enable plugin, so this could be actually reason for not populating with plugins data…

So I did so and enabled it also for one of feed too. Let’s see if it helps.
