![]() ![]() ![]() There are numerous developer tools out there but one important one is database software. DROP INDEX IF EXISTS public.MacOS is an extremely popular platform for developers, and the system is used across the world as a developer's first choice to work. DROP INDEX IF EXISTS public."photos_libraryId_idx" ĬREATE INDEX IF NOT EXISTS "photos_libraryId_idx" DROP INDEX IF EXISTS public."photos_bookId_idx" ĬREATE INDEX IF NOT EXISTS "photos_bookId_idx" REFERENCES public.libraries (id) MATCH SIMPLEĬONSTRAINT "photos_userId_fkey" FOREIGN KEY ("userId") REFERENCES public.library_books (id) MATCH SIMPLEĬONSTRAINT "photos_libraryId_fkey" FOREIGN KEY ("libraryId") REFERENCES public.books (id) MATCH SIMPLEĬONSTRAINT "photos_libraryBookId_fkey" FOREIGN KEY ("libraryBookId") "processingStatus" "PhotoProcessingStatus" NOT NULL DEFAULT 'UNPROCESSED'::"PhotoProcessingStatus",ĬONSTRAINT "photos_bookId_fkey" FOREIGN KEY ("bookId") Url text COLLATE pg_catalog."default" NOT NULL, Id integer NOT NULL DEFAULT nextval('photos_id_seq'::regclass), (slug COLLATE pg_catalog."default" ASC NULLS LAST) DROP INDEX IF EXISTS public.books_slug_key ĬREATE UNIQUE INDEX IF NOT EXISTS books_slug_key WHERE meta !~~ 'foo%'::text AND meta 'bar'::text (meta COLLATE pg_catalog."default" ASC NULLS LAST) DROP INDEX IF EXISTS public.books_meta_partial_exclude_foo_and_bar ĬREATE INDEX IF NOT EXISTS books_meta_partial_exclude_foo_and_bar Index: books_meta_partial_exclude_foo_and_bar DROP INDEX IF EXISTS public.books_fts_idx Tsv tsvector GENERATED ALWAYS AS (to_tsvector('english'::regconfig, ((COALESCE(title, ''::text) || ' '::text) || COALESCE(authors, ''::text)))) STORED, "updatedAt" timestamp(3) without time zone NOT NULL, "createdAt" timestamp(3) without time zone NOT NULL DEFAULT CURRENT_TIMESTAMP, "desc" text COLLATE pg_catalog."default", Slug text COLLATE pg_catalog."default" NOT NULL, Title text COLLATE pg_catalog."default" NOT NULL,Īuthors text COLLATE pg_catalog."default" NOT NULL, ![]() Id integer NOT NULL DEFAULT nextval('books_id_seq'::regclass), Timing: Generation 39.565 ms, Inlining 839.818 ms, Optimization 765.817 ms, Emission 599.027 ms, Total 2244.228 msĮDIT 2: adding information on table structure, indexes, and the query itself - Table: public.books Output: photos.id, photos.url, photos.type, photos."userId", photos."libraryId", photos."bookId", photos."libraryBookId", photos."isPrimaryPic", photos."processingStatus", photos."createdAt", photos."updatedAt", photos."otherData" Options: Inlining true, Optimization true, Expressions true, Deforming true Join Filter: (photos."bookId" = books.id) Output for EXPLAIN (ANALYZE, BUFFERS, VERBOSE) for query 1 (seqscan on does not use index). The cost estimate for the second plan is lower than that for the first, however, pg only chooses the second plan if forced to do so (by turning seqscan off).ĮDIT: Updating the question with information requested in a comment: I have the following 2 query plans for a particular query (second one was obtained by turning seqscan off): ![]()
