Unknown alias error when using Group By

[jasonsilvers-dispel]

Describe the bug

Not sure if it is a bug or just something pg-mem doesn't support yet.

QueryError: select "devices".*, COALESCE(json_agg(DISTINCT acl_rules.id) FILTER (WHERE acl_rules.id IS NOT NULL), '[]') as acls from "devices" left join "acl_rules" on "acl_rules"."device_id" = "devices"."id" where "facility_id" in ($1) group by "devices"."id" - Unknown alias "devices"

    🐜 This seems to be an execution error, which means that your request syntax seems okay,
        but the resulting statement cannot be executed → Probably not a pg-mem error.

    *️⃣ Failed SQL statement: select "devices".*, COALESCE(json_agg(DISTINCT acl_rules.id) FILTER (WHERE acl_rules.id IS NOT NULL), '[]') as acls from "devices" left join "acl_rules" on "acl_rules"."device_id" = "devices"."id" where "facility_id" in ('1') group by "devices"."id";

To Reproduce

import { newDb } from "pg-mem";

const database = newDb();
const db = database.adapters.createKnex();

await db.schema.createTable('devices', (table) => {
      table.increments('id').notNullable().primary();
      table.json('protocols_ports');
      table.string('name');
      table.string('make');
      table.string('model');
      table.string('ip');
      table
        .uuid('wicket_id')
        .notNullable()
        .references('id')
        .inTable('wickets')
        .onUpdate('CASCADE');
      table.dateTime('created_at');
      table.dateTime('updated_at');
      table
        .integer('facility_id')
        .notNullable()
        .references('id')
        .inTable('facilities');
    });

    await db.schema.createTable('acl_rules', (table) => {
      table.increments('id').notNullable().primary();
      table.string('remote_id').notNullable();
      table.string('source_ip').notNullable();
      table.string('destination_ip').notNullable();
      table.string('protocol').notNullable();
      table.string('ports');
      table.dateTime('created_at');
      table.dateTime('updated_at');
      table.boolean('is_paused').notNullable().defaultTo(false);
      table.integer('region_id').references('id').inTable('regions');
      table.uuid('user_id').notNullable().references('id').inTable('users');
      table
        .integer('device_id')
        .notNullable()
        .references('id')
        .inTable('devices');
      table.boolean('manual').notNullable().defaultTo(true);
      table.unique(['device_id', 'user_id', 'protocol', 'ports']);
    });

knex.destroy();

select devices.*,
COALESCE(json_agg(DISTINCT acl_rules.id) FILTER (WHERE acl_rules.id IS NOT NULL), '[]') as acls
from devices
LEFT JOIN acl_rules ON devices.id = acl_rules.device_id
where facility_id in (38, 39)
group by devices.id

This query works on postgres but fails with pg-mem

pg-mem version

"version": "2.6.13",

Bumping this thread...

It is happening to me too. The query works perfectly fine when executing directly on PostgreSQL, but it's failing when using Knex.
