Do we really need to be that verbose? Why not start with the minimal $$
and extend only if needed? On the KISS principle, trying "$$", "$X$",
"$XX$", "$XXX$", etc seems sufficient.
For that matter, I'm not convinced we should use $$ for comments. They
don't have nearly the problem that functions do with embedded quotes.
A thought: maybe just put this logic into the regular
appendStringLiteral routine, and trigger it when the string contains any
quotes or backslashes; if it has none, you can just use quotes ...
BTW, I've been holding off making this change myself, realizing that it
will completely break backwards compatibility of pg_dump output to 7.4
and earlier. Not sure if anyone is trying to use CVS tip pg_dump with
older releases, but it seems possible given that the dump ordering issue
is finally solved. Might be a good idea to make it disablable with a
fallback to regular quoting.
