Issue description

Describe your problem

wal-g doesn't open PPROF endpoint for postgresql databases

Please provide steps to reproduce

I run backup-list command because wal-g is stuck without any log messages and I want to know why. So I point http address for PPROF and enable it by switching on HTTP_EXPOSE_PPROF flag.

$ HTTP_EXPOSE_PPROF=true HTTP_LISTEN=0.0.0.0:9090 wal-g --config /etc/postgresql/walg.json backup-list

Then I try to open localhost:9090/debug/pprof but it doesn't work: I see UNABLE TO CONNECT in browser.

Because pprof is not opened for postgresql.
