 * Plugin to interact with the supabase Postgrest API

 * ```kotlin
 * val supabase = createSupabaseClient(supabaseUrl, supabaseKey) {
 *    install(Postgrest)
 * }
 * ```
 *
 * then you can use it like this:
 * ```kotlin
 * val product = supabase.postgrest["products"].select {
 *    Product::id eq 2
 * }.decodeSingle()
