As one who was about to ask the same question, I can provide one reason:
ease of use/administration. I can create everything I need to
manage/process my database *in* my database, rather than in numerous
shell scripts scattered about. I had a weird issue with cron recently.
I needed to do some db maintenance and wanted to make sure no one was
going to change it, so I removed all cron jobs (crontab -r). Halfway
through, suddenly the database started getting updated!! I finally
figured out that my predecessors, for some reason, had stuck a couple
cron jobs in the root crontab, which I corrected. And of course, if I
copy a database someplace, the jobs would go with it; not so cron jobs.
Now having said this, I realize that even if a scheduler was added to
PostgreSQL, there is nothing to stop someone from additionally using
cron jobs anyway. But there would be less temptation to do so.
