quoting psql varible as identifier

Hello

I am working on new patch. I see a problem with copy quote_ident on
client side. This function call ScanKeywordLookup function.

                const ScanKeyword *keyword = ScanKeywordLookup(ident,

                                    ScanKeywords,

                                    NumScanKeywords);

so we cannot simply implement quote_ident on client side :(. So we
have to use a real query.

It is acceptable for you?
