Real config values for bytes needs quotes?

Hello.

I found it frustrating that the line "shared_buffers = 0.1GB" in
postgresql.conf postgresql.conf was causing an error and that the
value required (additional) surrounding single quotes. The attached
patch makes the parser accept the use of non-quoted real values
followed by a unit for such variables. I'm not sure if that syntax
fully covers the input syntax of strtod, but I beieve it is suffucient
for most use cases.

Is the following a correct English sentense?

Do you folks think this makes sense?

regards.
