suite for ordering by an unqualified identifier reference and for DISTINCT ON,
alongside the existing ticket.status orderBy coverage. Reuse the established
Ticket query and assertions, ensuring both renderer paths verify the expected

…ay_position in ORDER BY `ORDER BY`/`DISTINCT ON` on a `pg.enum(...)` column rewrote to `array_position(ARRAY[...]::text[], <col>)` with no cast on the column argument, so Postgres rejected it with 42883 (no `array_position(text[], <enum>)` overload) — ordering by any native-enum column failed at runtime. Gate the rewrite on the column's codec (`pg/enum@1`) rather than on the mere presence of a value-set: a native enum already sorts by declaration order under a plain column reference (Postgres orders by `pg_enum.enumsortorder`), so it now falls through to plain-column rendering instead. Text-backed value-sets (CHECK-constraint enums) are unaffected and keep the `array_position` rewrite.

Removes the explanatory comments added in the previous commit and replaces the hand-built AST/migration integration test with an ORM-level port test that seeds rows and orders by the enum column through the public facade.

The suite is not a port of an upstream Prisma test, so it moves to its own directory. Adds a distinctOn case, which reaches the same rendering path through the public API.

The harnesses are generic, and two suites outside ports already reached into that directory for them. They move to test/_harness and every importer is repointed.

Summary
ORDER BYon a column typedpg.enum(...)rendered asarray_position(ARRAY[...]::text[], "col")with no cast on the column argument. Against a native Postgres enum column that is rejected outright:So ordering by any enum-restricted column failed at runtime on rc.8.
db.sqlfailed identically — it is the SQL renderer, not the ORM surface, so dropping to the SQL builder was not a workaround.Fixes #30163
The fix
Gate the
array_positiondeclaration-order rewrite off for native enums, rather than casting the column argument totext.A native Postgres enum already sorts by declaration order under a plain
ORDER BY— Postgres orders enum values bypg_enum.enumsortorder— so the rewrite is redundant there. It exists for value-sets backed bytext/varcharcolumns with a CHECK constraint, which would otherwise sort alphabetically. Those are unaffected: they carrypg/text@1, the gate is inert for them, and the existing declaration-order suite passes 7/7 unchanged.The alternative was casting the column inside
array_position. That also works — it preserves declaration order, it does not sort alphabetically — but it keeps a per-row function call that defeats a plain index on the column, and it leaves the renderer unable to distinguish "needs sort-order emulation" from "the database already sorts this correctly". Gating also agrees withrenderWhere, which renders comparisons on the raw column, so a keyset/cursor predicate already compares by enum ordering wherearray_positiondid not.Why it is safe
Contract declaration order and
pg_enum.enumsortorderare kept identical by the migration planner: it can only append a value (ALTER TYPE … ADD VALUE, noBEFORE/AFTER) and refuses any other member change — rename, removal, or reorder — vianativeEnumMemberChangeRefusal. If that refusal is ever relaxed to permit reordering, this gate has to be revisited.The gate keys on
codecId, notnativeType. A hand-authored contract carrying apg/text@1codec over a column whose adopted physical type happens to be a native enum would not be caught — reachable only by hand-adopting an existing enum type as text, not by anythingpg.enum(...)authoring produces.Interaction with #30099
#30099 ("enum ORDER BY / DISTINCT ON loses declaration order behind a derived table") touches the same function. This PR should land first — it is ~10 lines against a hard runtime error on a published release, while #30099 is larger and still in review.
#30099 deletes
TableSourceCoordinate/collectTableSourcesand both resolver functions here, replacing them withresolveColumnValueSetFromSource(source, column, contract)returning{ found, values }. On rebase, drop both call sites ofsortsByDeclarationOrderNativelyand call it once instead, in that PR'stable-sourcebranch, immediately afterstorageColumnis resolved:found: true, notfalse— the column exists, it is simply not rewritten, and the identifier resolver's ambiguity counter depends on that distinction. That single site also covers #30099's new derived-table recursion, which this PR's two call sites do not reach. Re-inserting the gate at the two old call sites instead would pass the tests here but leave a native-enum column behind adistinct()/groupBy()wrap as a new, untested 42883.Testing
test/integration/test/ports/prisma/functional/issues-30163-enum-order-by— an ORM-level port test. The harness pushes the contract through the plan → apply path (no hand-written DDL), then seeds rows and queries through the public facade:Declaration order is
open, closed, so alphabetical ordering is distinguishable from a correct sort. Ascending and descending are both asserted on the whole result shape. Against the renderer onmainboth cases fail with42883; with the fix both pass.The existing text-backed value-set suite (
order-by-enum.integration.test.ts) passes 7/7 unchanged, and the postgres adapter suite is green at 866 passed / 3 expected-fail.Release note
