Even "doing it right," postgres 7.2 was significantly slower than MySQL
for bulk data imports, at least for tables with relatively narrow rows.
I was going to put this down to higher row overhead, except that it was
nowhere near raw file I/O speed, either.
So this could use improvement, if it's not been improved already.
There's room for performance increases in a lot of other areas, too, but
in the end, a lot of people just don't design their databases for good
performance. And I've killed enough non-postgres database servers in my
life to know that if you don't really know what you're doing, you can
easily make the performance of any DBMS suck. :-)
Personally, I think there's still a fair amount of room in the features
area, too. I'm always running into something that I'd like to have.
Today it was being able to defer a UNIQUE constraint.
