Crosstab/Pivot in Postgres SQL

Question

I need to convert rows to columns in PostgreSql. It would be great if someone can put some shed on this. I tried to solve this using crosstab but no luck.

select *
from crosstab(
    'select
    count(distinct no_of_cars) as no_of_cars,
    car_type,
    month
from abc
group by 2, 3
order by 3',
    'select distinct month from abc order by month'
) as ct(
    no_of_cars text,
    car_type text,
    month text
) 

Attached Screenshot of the data.

Answer 1

I prefer filtered aggregation, as I find that to be easier to maintain and understand:

select car_model, 
       sum(no_of_cars) filter (where month = 'Nov-22') as "Nov-22",
       sum(no_of_cars) filter (where month = 'Oct-22') as "Oct-22",
       sum(no_of_cars) filter (where month = 'Sep-22') as "Set-22"
from the_table
group by car_model
