MySQL 3.23.29 is pre-InnoDB
(http://dev.mysql.com/doc/refman/4.1/en/innodb-in-mysql-3-23.html), so
this database is not transactional, not ACIDic, and does not support
row-level locking or foreign key referential integrity. At this point,
MySQL lacked support for subqueries, UNIONs, VIEWs, and nearly
everything else beyond basic CRUD.
I bet I can design a program that interfaces flat data files so fast it
makes any RDBMS pale in comparison. SQLite does that, and it's ACID
compliant! Performance is not the only motivation for using an RDBMS.
Data integrity and relational modeling are also big considerations.

in section PostgreSQL vs MySQL :
[quoting]
Regarding the choice between PostgreSQL and MySQL, MySQL is
recommended for several reasons:
* MySQL is faster
recent benchmarks using ZABBIX clearly show that PostgreSQL
(7.1.x) is at least 10 times slower than MySQL (3.23.29)
Note: These results are predictable. ZABBIX server processes use
simple SQL statements like single row INSERT, UPDATE and simple SELECT
operators. In such environment, use of advanced SQL engine (like
PostgreSQL) is overkill.
* no need to constantly run resource-hungry command "vacuum" for
MySQL
* MySQL is used as a primary development platform.
If you do use PostgreSQL, zabbix_server will periodically (defined in
HousekeepingFrequency) execute command vacuum analyze.

anybody know these guys? this is right off the mysql anti-postgresql
advocacy page.
