The quoting is used to specify a literal name. In particular, if you
specify something like:
Name varchar(32)
Without the quotes, this will be case-folded to all lower-case name.
If you use the quotes, the name will not be case-folded. As a general
RULE, if you use quotes anywhere, you should use them everywhere. Do
not mix-and-match or you will likely get into trouble.

I don't think so. You will probably want to look at using the psql
executable for mass- or automatic-processing of scripts.
