	--- PSQL queries which also duplicated from https://github.com/anvk/AwesomePSQLList/blob/master/README.md
	--- some of them taken from https://www.slideshare.net/alexeylesovsky/deep-dive-into-postgresql-statistics-54594192

	-- I'm not an expert in PSQL. Just a developer who is trying to accumulate useful stat queries which could potentially explain problems in your Postgres DB.
