It now has to construct a key/value pair with proper escaping (well, for this one flag it would be easy, but if we do that wouldn't we also support the other config params? Were you thinking we'd have *just* tihs one?). Basically taking a data that you have in a "structured format" in the btw already turning it to a string and then parsing it back into structured data in the same string. I think it'd be cleaner to let the bgw initializer pass those as flags. A "user connection" parameter could still use the booelan in InitPostgres() of course, and not invent a new things there, but the entry point API could stay simpler. I haven't actually looked into what it would look like, so it could be that I'm overestimating what it'd mean of course. -- Magnus Hagander Me: https://www.hagander.net/ <http://www.hagander.net/> Work: https://www.redpill-linpro.com/ <http://www.redpill-linpro.com/>
