Right; original Postgres used a query language called "POSTQUEL",
which was sort of like SQL but not compatible.

This I dispute. A lot of the core functionality has a very traceable
lineage back to original Postgres; even though some details of the code
may have been revised pretty heavily, the algorithms and design
decisions remain. This has good points and bad points ;-) ... but
it's absolutely not true that Postgres95 threw away the existing code
and started over. As you said yourself, it was more of a question of
sticking a new frontend (ie, parser) on the existing database engine.

MySQL simply did a better job of marketing themselves to an audience that typically doesn't know SQL or understand relational databases. MySQL focuses on speed as it's primary asset. Integration with quick growing languages (like PHP) helped a lot too. MySQL is also the product of an existing software company that employed basic marketing principles early in the game. Most of the web based projects I have found were obviously written by (good) programmers that just didn't have a grasp of relational data models. They just needed a quick & easy way to store large tables of information. (Berkley DBM's only go so far) Given that this "less DB savvy" audience didn't understand relational databases, things like triggers and decent SQL support don't strike them as important as speed. MySQL is a good migration path for xBase, and the multitude of DBM based scripts that were dominate a few years ago. PostgreSQL is the only path for someone that intends to use relational design in their applications. MySQL doesn't even come close. The bottom line is that the marketing of PostgreSQL is not even close to that of MySQL.

I think MySQL got a big start by migrating mSQL users years ago and having a compatibility module for mSQL. -- Bruce Momjian | http://candle.pha.pa.us pgman@candle.pha.pa.us | (610) 853-3000 + If your life is a hard drive, | 830 Blythe Avenue + Christ can be your backup. | Drexel Hill, Pennsylvania 19026

One great advantage of mySQL (and mSQL) ist the low connection-overhead. Especially in mSQL this was an explicit design-goal. In CGI-based WEB-environments it is very important that the time spent for connecting the database is as low as possible. Time wasted there cannot be autweight by fast SELECTS since many CGI do only very few SQL-statements. Using later WEB-techniques (as e.g. Servlets or Fast-CGI) this part becomes less important since an single DB-connection can be kept open across multiple WWW-requests. In applications where the connection is kept open for a long time the connection overhead becomes insignificant. Elmar
