Trivial doc patch

This removes the outer square brackets in the create_database.sgml
file's synopsis.  In the command sysopses, this is the only case
where an optional group contains only optional groups.

You are not wrong, and the existing doc is not wrong either.  I tend
to prefer the existing style, though, as it insists on the options
as being a single group, with or without the keyword WITH.

Michael, perhaps I mistake you; it seems you would like it better with
the extra '[' before OWNER.  That would more accurately point up

    CREATE DATABASE name WITH;

Either way, my argument would have the basis.

In what sense are the options a single group?  That they all might
follow the 'WITH' is expressed without the duplicated brackets.
That the extra braces promote readability relies on an assumption or
knowledge of the command.

Given that 'optional, optional' has no independent meaning from
'optional';  it requires one to scan the entire set looking for
the non-optional embedded in the option.  So no gain.

I originally had the same reaction Michael Paquier did, that having one
big optional block is nice, but seeing that 'CREATE DATABASE name WITH'
actually works, I can see the point in having our syntax be accurate,
and removing the outer optional brackets now does seem like an
improvement to me.

Attached is the proposed change.

Backpatched to PG 10.  Thanks.
