PostgREST.DbRequestBuilder

This module is in charge of building an intermediate representation(ReadRequest, MutateRequest) between the HTTP request and the final resulting SQL query.

A query tree is built in case of resource embedding. By inferring the relationship between tables, join conditions are added for every embedded resource.
