Does not repeat within the defined tsrange

[gajus]

select *
FROM
  occurrences('
    DTSTART:20200301T000000
    RRULE:FREQ=WEEKLY'::TEXT::rruleset, tsrange('2020-03-01 00:00', '2021-04-01 00:00'));

Produces:

"occurrences"
"2020-03-01 00:00:00"
"2020-03-08 00:00:00"

I expect to get 57 rows (as there are 57 weeks in the time range), but I am only getting 2 rows.

Adding an arbitrary large COUNT "fixes" the problem.

select *
FROM
  occurrences('
    DTSTART:20200301T000000
    RRULE:FREQ=WEEKLY;COUNT=1000'::TEXT::rruleset, tsrange('2020-03-01 00:00', '2021-04-01 00:00'));

same here. We almost only create weekly events in our app so I set the count to 50,000 for "infinite" series.
