Walkthrough
Merge Risk: 🔵 Low · up to The API change is otherwise localized, but the migration guide should explain that Operator(rawValue:) is now non-failable so downstream call sites can be updated without compilation surprises. The PR is mergeable with explicit owner follow-up on this documentation gap. ✨ Finishing Touches 💡 1🛠️ Fix failing CI checks 💡

…esentable struct Operator is part of the public API surface; as an enum, using an operator PostgREST added after this SDK version shipped required an SDK upgrade even for a value that just needed constructing. CaseIterable is dropped with no replacement. See SDK-637.

| ## `PostgrestFilterBuilder.Operator` is now a struct, not an enum | ||
|
|
||
| `PostgrestFilterBuilder.Operator` (passed to `not(_:operator:value:)`) is a `RawRepresentable` | ||
| struct instead of an `enum`. It no longer conforms to `CaseIterable`. | ||
|
|
||
| It's sent to PostgREST as part of a filter query string, not decoded from a response, but it's | ||
| part of the public API surface — as an `enum`, using an operator PostgREST added after this SDK | ||
| version shipped required an SDK upgrade even though constructing the value doesn't need one. | ||
|
|
||
| ```swift | ||
| // Before | ||
| switch op { | ||
| case .eq: ... | ||
| case .neq: ... | ||
| // ... | ||
| } | ||
|
|
||
| // After | ||
| switch op { | ||
| case .eq: ... | ||
| case .neq: ... | ||
| // ... | ||
| default: ... // an operator the SDK doesn't have a case for | ||
| } | ||
| ``` | ||
|
|
||
| Compile error only if you have an exhaustive `switch` over `Operator` — add a `default:` case. | ||
| `Operator.allCases` no longer exists, with no built-in replacement — maintain your own array if you | ||
| were relying on it. Passing a known operator (`.eq`, `.gt`, ...) works unchanged. |

Document the changed rawValue initializer.
Operator(rawValue:) was previously failable because it was synthesized for the String enum. It is now non-failable at Sources/PostgREST/PostgrestFilterBuilder.swift lines 95-97. Existing if let and guard let call sites will not compile. Add this migration step and show direct initialization.
As per coding guidelines, “Check for breaking API changes during code review.”

Summary
PostgrestFilterBuilder.Operator(25 filter operators —eq,neq,gt, ...wfts) from aStringenum to aRawRepresentablestruct. NoCodable— the original enum wasn't either (.rawValueis read directly into a filter query string). DropsCaseIterablewith no replacement.Tests/PostgRESTTests/BuildURLRequestTests.swift'sOperator.allCasessnapshot-test loop is replaced with an explicit array in the exact same order — the recorded snapshot is byte-for-byte unchanged.V3_MIGRATION.mdsection. This is the first PostgREST-module PR in this stack.Part of SDK-637 — PR 11 of 15. Stacked on #1224 (
SignOutScope, last Auth-module PR); review that first. This PR and everything after it touch onlyPostgREST/Functions, no further overlap with Auth.Test plan
Tests/PostgRESTTests/OperatorTests.swift: string-literal construction, hashability, raw-value uniqueness across all 25 cases.PostgrestFilterBuilderTests/BuildURLRequestTestssnapshot unchanged — verified byte-for-byte.PostgRESTTestssuite passes (120/120), no regressions.
