PostgreSQL extensions must be enabled in your database before you can use them. To enable the extension, run the command from the psql tool to load the packaged objects into your database.postgresql Kopiraj SELECT CREATE_EXTENSION('vector'); ...
postgresql DELETEFROMtblvectorWHEREid =1; To retrieve vectors and calculate similarity, useSELECTstatements and the built-in vector operators. For instance, the query computes the Euclidean distance (L2 distance) between the given vector and the vectors stored in thetblvectortable, sorts the results...
