Hi,I found that if I have change the wal-segsize in 32MB or 64MB during compile source code， the postgres_exporter will start up fail by Unknown unit for runtime variable:"32MB".
I found the reason that the unit does not supported by '32MB' or '64MB' from the query
SELECT name, setting, COALESCE(unit, ''), short_desc, vartype,* FROM pg_settings WHERE vartype IN ('bool', 'integer', 'real').
