PostgREST access: select, insert, update, delete, upsert, count/range reads, and RPC (rpc / rpcGet), all driven by the type-safe filter DSL (eq, neq, gt, like, ilike, in, is, textSearch, contains, ordering, limits). Each call returns a SupabaseResult, so errors carry a category instead of throwing.

Coordinate: io.github.androidpoet:supabase-database

import io.github.androidpoet.supabase.database.createDatabaseClient

val database = createDatabaseClient(client) // client from supabase-client

database.select(table = "todos") {
    eq("done", "false")
    order("created_at", ascending = false)
    limit(25)
}.onSuccess { json -> println(json) }
 .onFailure { error -> println("query failed: ${error.message}") }

select returns the raw response body as a SupabaseResult<String>; decode it with kotlinx.serialization (typed selectTyped / insertTyped extensions are available for @Serializable models).

Targets: Android, JVM, iOS, macOS, tvOS, watchOS, Linux, Windows, WasmJs.

Note: Filters are applied inside the trailing filters { ... } lambda; an empty lambda fetches all rows (subject to your RLS policies).
