@pengweiqhca Why we need new project MicroOrm.Dapper.Repositories.Tests2? Maybe we can use one project for tests?

1. Test the different driver of mssql, mysql and sqlite.
2. postgres bool and oracle bool not compatible in same process.

If use one project, will use different TargetFramework. Use two project or two TargetFramework?

@pengweiqhca I can check/test it only next week. Add PostgreSql to docker-compose.yml, please.

I will think about splitting tests per Provider.
