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.
