there are two quoting styles, so we need two syntax. I proposed
:[var] and :{var} - for ident quoting and literal quoting.
Theoretically we could to use :(var) for bytea escaping. :!foo isn't
good idea. It is related to negation operator. Bracket or parenthesis
are good readable and far to some custom pg operators.
