I-PostgREST yiseva yewebhu evulekileyo ekuvumela ukuba uguqule nayiphi na isiseko sedatha egcinwe kwi-PostgreSQL DBMS ibe yi-RESTful API epheleleyo. Inkuthazo yokubhala iPostgREST yayingumnqweno wokumka kwiprogram ye-CRUD ye-manual, njengoko oku kunokukhokelela kwiingxaki: ukubhala ingqiqo yezoshishino kudla ngokuphindaphinda, ukungahoywa okanye ukwenza nzima ukwakhiwa kwedatha; i- object-relational mapping (ORM mapping) luthango olungathembekanga olukhokelela kwikhowudi enyanzelekileyo ecothayo kwaye inokubangela iingxaki zokhuseleko. I-PostgREST ibhalwe kwi-Haskell kwaye isasazwe phantsi kwelayisensi ye-MIT.
