Can't change `postgres.conf` values

[subhan-nadeem]

I want to override in the MAX_CONNECTIONS variable which is located in RuntimePath/postgresql.conf. The problem is, this value needs to be overridden prior to the DB process starting in order to take effect. postgres.Start() clears RuntimePath directory, which doesn't allow a custom postgresql.conf to be injected. There's also no restart mechanism that would utilize the same postgresql.conf file without wiping RuntimePath.

Hey @subhan-nadeem, apologies for the delay in responding.

This sounds like a generic beforeStart() sort of method would be useful, which took an anonymous function? I'm a bit short on time but if you think you could do something around this I'd welcome a pull request with the additional feature.

Cheers

I added #102 as a proposed fix for this issue.

It takes the approach of feeding configuration values to postgres on the command line at startup. I think that is probably easier than adding a hook for file placement (both for this library to implement and for clients to use).
