bug(frontent): generate_series not compatible with PSQL

[CAJan93]

Describe the bug

https://www.postgresql.org/docs/current/functions-srf.html

Postgres supports 2 forms of generate_series: One with 2 params and one with 3 params. The 3rd params is the stepping distance between the generated numbers

SELECT * FROM generate_series(2,4);
 generate_series
-----------------
               2
               3
               4
(3 rows)

SELECT * FROM generate_series(5,1,-2);
 generate_series
-----------------
               5
               3
               1
(3 rows)

We only support the version with 3 params. Should we also support the one with 2 params?

It just defaults to 1 for the stepping distance.

Expected behavior

Compatibility with PSQL

Should we also support the one with 2 params

Yes
