PgEnumSerializer

Writes a registered enum into JSON under the label PostgreSQL holds, and reads it back.

The driver's enum converters answer for an enum column; nothing about them reaches a value that travels as JSON instead, where kotlinx.serialization writes the Kotlin constant's own name. That leaves one value spelled two ways depending on where it is stored, and a query filtering on payload ->> 'office' matching neither reliably.

It is built from the registration and not from an annotation, so the enum named at registerEnum and the one a classpath scan found by @PgEnumType are covered alike: both arrive in the driver's registry the same way, carrying the conventions they were registered under.
