Depends on how you define "correctly" ;-) Chances are that it will raise an error.
I'm not sure if this should really be considered a problem; that's a really obtuse SQL statement. As a non-pgsqler, I have a hard time figuring out where the variables are. I welcome native postgres prepare/bind/execute support, and don't mind adjusting the pdo_sql_parser.re code to cater for rewriting ? or :named style substitutions into postgres style; it already includes some logic for rewriting ? to :named and vice-versa, so the modifications should be reasonably simple. --Wez.
