MySQL vs PostgreSQL on Windows
asp.net, c#, mysql, postgresql
Solution
AFAIK either one of them should work fine if your requirements are fairly low. If you want to use more advanced db stuff, PostgreSQL is probably the better choice, but for simple stuff it doesn't really matter.
My recommendation is to pick the one you have experience administering, or that is used elsewhere in the organization.
Problem
I am torn between PostgreSQL and MySQL. I am forced to install the chosen one on Windows. I especially need ASP.NET Membership and NHibernate as well.
