Consider you have following dataset.

Query:
{noformat}
SELECT t0.mailbox_id, t0.mail_uid, t0.mail_is_answered, t0.mail_body_start_octet, t0.mail_content_octets_count,
t0.mail_is_deleted, t0.mail_is_draft, t0.mail_is_flagged, t0.mail_date, t0.mail_mime_type,
t0.mail_modseq, t0.mail_is_recent, t0.mail_is_seen, t0.mail_mime_subtype, t0.mail_textual_line_count
FROM public.james_mail t0 WHERE (t0.mailbox_id = 1 AND t0.mail_uid >= 1 AND t0.mail_uid
<= 18) LIMIT 200
{noformat}

Result against the preceding query:
{noformat}

mail_is_draft	mail_is_flagged	mail_date	mail_mime_type	mail_modseq	mail_is_recent	mail_is_seen

{noformat}

Note that the dataset doesn't ordered by mail_uid. with that dataset, the IMAP server returns
following response:

{noformat}
3 uid fetch 1:* (FLAGS)
* 1 FETCH (FLAGS (\Seen NonJunk) UID 1)
* 2 FETCH (FLAGS (\Seen NonJunk) UID 2)
* 3 FETCH (FLAGS (\Seen NonJunk) UID 3)
* 4 FETCH (FLAGS (\Seen NonJunk) UID 4)
* 5 FETCH (FLAGS (\Seen NonJunk) UID 6)
* 6 FETCH (FLAGS (\Seen NonJunk) UID 5)
* 7 FETCH (FLAGS (\Seen) UID 17)
* 8 FETCH (FLAGS (\Seen NonJunk) UID 18)
3 OK FETCH completed.
{noformat}

I believe the server should return all of dataset, but records that has mail_uid larger than
18 were skipped.
