It seems to me that this should absolutely go on the TODO list. Why does the planner require an explicit cast when the
implicitcast is so obvious? Does Oracle do this? I can assure you that MSSQL does not.
If getting more people to migrate to PostgreSQL is a major goal these days, it's got to be relatively easy. I think
thatalmost everyone coming from a MSSQL or Access background is going to have big problems with this. And the other
issueof the JOIN syntax constraining the planner - you've got to be able to turn that off too. I've been writing SQL
queriesfor 10 years in FoxPro, Access, SQL Server, MySQL, and Sybase. I have never come across this very confusing
"feature"until now.
How do we go about voting an issue onto the TODO list? These two get my vote for sure!
