Ugh. It's a long and hairy query that would be a nightmare in a format statement.
Assuming you can pass this thing into the crosstab function in the first place you must already have put it into a string. Changing "crosstab" to "format", plopping in the placeholders, and adding a couple of more passed-in arguments is not materially more effort or hairier.
You could create a SRF for the pre-crosstab data then do: SELECT crosstab('select * from table_func(%,%,%)', :'dd', ...). The table_func itself would then just use pl/pgsql variables (or SQL ones...) in a normal query instead of a dynamic query (presuming you are only substituting values anyway).
