Good question. It would theoretically work with Postgres with a fair
amount of code modification, using COPY instead of LOAD DATA for the
imports, and an ODBC connection for Sphinx. However, it would be a
lot less time to install MySQL and gain a cursory knowledge of it than
to modify all of the code the allow for Postgres. The other issue is
that Postgres would be much slower in this case because the MySQL
native connections in Sphinx are much faster than the ODBC connections
(something like 50k rows/sec versus 6k rows/sec for indexing), and
MyISAM tables are simpler than transaction-oriented tables, so they
load data faster. Lastly, you'd lose the ability to archive logs, as
it uses the MySQL ARCHIVE storage engine which provides an incredible
compression ratio because it compresses an entire 32k chunk of table,
not string by string.

I would strongly urge you to try MySQL instead of modifying the code.
It should install very quickly on almost any platform and there won't
be much tuning or administration required.
