without knowing the hardware organization & availability of software,
it's seems strange that you're considering different database systems
for things that one is perfectly capable of performing.  it's a bit of a
fallacy that MySQL is better for read only database sites.  on the low
end (fewer connections), MySQL might be faster, but you'd have trouble
buying hardware that was slow enough that you'd notice the difference.
i've never used MySQL on a heavily loaded web site, but i've heard
enough about MySQL breaking down to be a bit concerned about that.  all
in all, i'm just not clear on why you're interested in the added
headache of multiple database systems & copying data between them.

As I said in my first email, it just depends :).  I do plan on doing
tests against MySQL and Postgrest to see which would be better for
just serving out dynamic content (read only).  Whichever one wins
out will be the one i'm going to use.  Personally, I've had no problems
at all with MySQL...I'm looking into postgres because MySQL won't
do the things I need to do on my next product version.  And, the
data won't be copied between the 2, MySQL will be dumped to, and thats
it. So there won't really be much headache on that part.  When the time
comes, I'll choose.  Currently, I'm just planning ahead.

Thanks,

    We actually have a split shop here, because I set up the bug database
in postgres, and we later hired a web guy who was more familiar with MySQL.
He has since seen the light and converted much of his stuff to use Postgres,
but there are some semi-remote machines using MySQL.  With PHP, even though
there is almost no consistency between database interfaces, it isn't too
hard to use both systems.

    I still reccommend going with one database solution, though.  Much
easier to set up, maintain, etc.  I don't trust MySQL, so I'll let
you guess which one I reccommend...

I recently worked on a project in which it was necessary to source data
on a daily basis across the organisation from a variety of sources: Oracle,
SQL server (both 6.5 and 7) and various flat files (each system was
developed
and maintained by relatively autonomous business units). In this case, the
choice of DB was out of my control (it was an M$ shop through & through), so
PostgeSQL was out of the question. If things had been different in this
situation, it would have been very handy to be able to talk to the other
DBs via PostgreSQL.
