Regex patterns don't have the notion of a quoted substring at all, so
it seems moderately unreasonable to me to expect dollar quoting to mean
something to regex (even discounting the fact that it couldn't work
lexically because $ has different lexical properties in a regex
pattern).

The dollar quote stuff is documented as a SQL string constant
representation.  It doesn't seem to me that you'd expect it to work
anywhere except in SQL statements.
