Habr 25+[Перевод] Нетипичные оптимизации в PostgreSQL, или Креативное ускорение запросов
Когда речь заходит об оптимизации базы данных, разработчики обычно перечисляют привычный набор приёмов: слегка переписать запрос, накинуть индекс на колонку, денормализовать, сделать analyze, vacuum, cluster, и так по кругу. Классические техники, конечно, работают, но иногда креативный подход даёт гораздо больше. В этой статье Haki Benita показывает нетипичные техники оптимизации в PostgreSQL.

In 1951 G.V. Carey published a 15-page booklet called “Making an Index,” intended to guide new authors in preparing indexes for their books. When it was published, a friendly (.) suggested jokingly that the booklet might have benefited from an index of its own, in which Carey could have given “a full-dress demonstration of his principles.”
So, charmingly, Carey made one."

As You Wish - Futility Closet
In 1951 G.V. Carey published a 15-page booklet called “Making an Index,” intended to guide new authors in preparing indexes for their books. When it was published, a friendly reviewer in the Times Literary Supplement suggested jokingly that the booklet might have benefited from an index of its own, in which Carey could have given “a full-dress demonstration of his principles.” So, charmingly, Carey made one: In the second edition he added a 3-page index to his 15-page book, writing, “The reviewer, though he may have had his tongue in his cheek, has put the author on his mettle and...
This leads me to the discovery of the scholarly journal The Indexer, still going strong since the 1950s and asking pointed questions.

"An index is customarily regarded as an arrangement of signposts pointing the way to alphabetically analysed textual content, but may effectively serve more imaginative purposes: to relieve the text of overburdening detail, to replace footnotes, to sharpen the perspective of the text, to supplement as well as elucidate textual content. Above all, it may be made so readable that one may begin with the index, deriving from it such pleasure as will stimulate eagerness to turn back to the text, perhaps piecemeal rather than as a continuous whole. (...)
In summing up my ideas with regard to the unconventional Index, I would say that I can imagine that a mechanized, computerized Index may have its function, and that is to satisfy the mechanized, computerized human minds and their particular, totally legitimate intellectual needs. The type of Index I have in mind should be more than the carefully tended cemetery of the ideas expressed in the to-be-indexed text. (...) Ideally, then, a good Index should be more than merely a taciturn sign-post erected after all the rest has been done and is immutably crystallized. Otherwise we get the ordinary Feld-Wald- und Wiesen-Index which tells the reader how many kilometres he has to proceed in which direction, and at which locality he will receive further information, with the usual infras and supras, the ridiculous op.cits, the obscure qua voces, and the tantalizing see alsos. I prefer the Index which has a life of its own, which may pride itself on being the child of imagination, and which should enable us to spend a peaceful evening in bed, reading such an Index, as if we were reading a good novel."
