Re: massive quotes?

These approaches are to some extent orthogonal, ISTM. Maybe the best
solution would be to do as Tom suggests and just change psql (and, I
would add, pg_dump) to act nicely here, and if other interface
users/authors need/want something along these lines re-examine the
issue. I use JDBC for my web clients in my current project, but I
wouldn't create a function in the client. I probably wouldn't using
DBI/DBD:Pg either. So taking myself as a sample of one perhaps it is
true that it's only needed in psql :-)

I'm all for minimal solutions as long as they look nice.
