It seems to me, with some of the most popular database servers (Oracle, MS-SQL Server, MongoDB, PostgreSQL, MySQL/MariaDB) that it may serve to have a dedicated site for those servers? Maybe just an "sql.stackexchange.com" site?
I was specifically wanting to find a canonical example of getting PostgreSQL setup with PLV8 and wasn't even sure where to ask. In my case, Ask Ubuntu may have been best, I was just thinking with the number of database administrators, and devops types in this network that it would be a good idea to have a separate site.
There are many SQL ops questions that aren't OS specific, or aren't really development questions... where do these go?
