Below is a post from the Fedora mailing list as to why one of the users
recommends Firebird over PostgreSQL (this thread came up because of
questions regarding MySQL licensing) and I was wondering if someone from
pgsql advocacy had any comments on this or would like to respond.
Sorry for top posting, but I didn't want to ruin any formatting.

I like PostgreSQL as far as it's simplicity and things go. It's nice,
and there are some good front ends for it. The one complaint I have
with Postgres is that it forks.
MySQL and Firebird use threads and Postgres forks. Forking is ok,
unless you have many database connections. The more connections the
more processes. I noticed while profiling an application that every
connection alone was taking over 1MB of memory. This based on the
process per connection gripe I have.
So, Postgres, sure I like it, but as far as a major DBMS goes, I think
it is limited by it's memory usage. That's just my opinion on the
matter. However, it is a fact that it forks (forking takes more time
and more resources than threading). One benefit in forking is the same
reason Apache forks( memory leaks can be minimized). However, I think
if a DBMS has that bad of a memory leak....I won't use it.
I like to advocate Firebird as much as possible. It runs on many
platforms and seems to be pretty scalable as far as connections and
usage goes, and it has a very flexible license as well.
I like all three mentioned DBMS, just different reasons for using them
at different times.
