Most other databases are more forgiving of bad queries. Make a bad query and postgresql is more likely to punish you for it.
Amen. When I migrated from MSSQL to PostgreSQL (4 years ago), I found out exactly how seriously MS SQL coddles you when it comes to its "Oh, I know what you really meant" query planning. I committed some sins MS SQL covered up nicely and PostgreSQL flat out crawled when presented to it. However, I suspect that if I tried those bad queries with a current version of PostgreSQL they would run much better, given all the work that has been put in over the last few years. - Ian
