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.
