@uwedeportivo Can a user specify PG* variables here individually instead of a DSN? Composing the DSN requires hard-coding the password or some weird trickery if it contains values that need to be URL-encoded

I imagine the same would be true in deploy-sourcegraph; we should probably just use the PG* variables mirroring the frontend
