One way would be:
```
with series(value)
as (
select 1
where exists (
select *
from EventTable
where EventType = 35
)
union all
select value + 1
from series
where value < (
select max(Details)
from EventTable
where EventType = 35
)
)
select value from series;
```
or, if using the generate_series (series.c) extension:
```
select value
from generate_series
where start = 1
and stop = (
select max(Details)
from EventTable
where EventType = 35
);
```
