This PR introduces a change for excluding "own queries" in postgres from `pg_stat_activity`: we need to drop samples (and wait events) for the currently connected user. This new behaviour is enabled by default through the setting `exclude_current_user`, as it's deemed safe / recommended. No changes to be done on `pg_stat_statements` as that is achieved through user permissions update (docs on the website).

Drive-by change: I've tried to fix flakyness of these tests and make the style more consistent.
