Postgres can write multiline logs, and they are difficult to handle
after they are mixed with other logs. This PR combines multiline logs
from postgres into a single line, where previous line breaks are
replaced with unicode zero-width spaces. Then postgres logs are written
to stderr with `PG:` prefix.

It makes it easy to distinguish postgres logs from all other compute
logs with a simple grep, e.g. `|= "PG:"`
