`It's the first guy to publicly say "the emperor is naked"' That MySQL has a poor optimizer has been known for as long as MySQL has been a product. The product is legendary for its inability to do even basic RDBMS needs competently, and the rise of NoSQL was largely people assuming MySQL limitations were general RDBMS problems (for instance its painful incompetence doing basic RDBMS tasks like joins). Having said that, a couple of decades in this industry has me reading this post and immediately sensing oozing bitterness. That maybe he got passed over for a promotion he felt he earned, etc. When someone does the "it's all crap" exit, it's seldom from a good place. Who could seriously have applied to and joined the MySQL team without knowing that it isn't exactly the pinnacle of database systems? Having said all of that, it's interesting seeing pgsql being held as the panacea. I like pgsql, and prefer it among open source database systems, but in many ways it is a decade+ behind MSSQL and Oracle.
