/**
 * ConnectionFilterComputedAttributesPlugin
 *
 * Adds filter fields for computed columns (PostgreSQL functions that take
 * a table row as their first argument and return a scalar).
 *
 * For example, given:
 *   CREATE FUNCTION person_full_name(person) RETURNS text AS $$ ... $$;
 *
 * This plugin adds a `fullName` filter field to `PersonFilter`, typed as `StringFilter`,
 * allowing queries like:
 *   { people(where: { fullName: { startsWith: "John" } }) { ... } }
 *
 * Controlled by the `connectionFilterComputedColumns` schema option (default: true).
 * Requires the `filterBy` behavior on the pgResource to be enabled.
