+"""tag_vertical_counts bez klucza obcego do tags (zakleszczenie o 05:00, Sentry GOON-7N).
+
+Codziennie o 05:00 rusza naraz refresh_taxonomy_counts (co 3 h) i tag_tail_trim (raz
+dziennie). Przycinanie kasuje przypisania rule34video, a potem osierocone tagi; DELETE na
+tags schodzi kaskada do tag_vertical_counts i czeka na refresh, ktory te wiersze wlasnie
+podmienia. Refresh wstawia liczniki z migawki, w ktorej skasowane przypisania jeszcze sa,
+a sprawdzenie klucza obcego czeka na blokade tego samego wiersza tags. Od 2026-09-29
+Postgres co rano zabija tag_tail_trim.
+
+Tabela to kopia liczona od zera co 3 h, wiec klucz obcy nic nie daje: wiersz po
+skasowanym tagu znika przy nastepnym odswiezeniu, a /tags i tak zaczyna od tabeli tags.
