I tested with raising syntax errors first but the resulting code was a bit more ugly and the sql checking under a error condition (i.e. double named parameter error means there is one parameter in short)  was causing serious errors.

I've tested this patch out and can confirm mixed notation produces an error:

psql:plsqltest.sql:27: ERROR:  mixing positional and named parameter assignment not allowed in cursor "cur1"
LINE 10:       open cur1( param2 := 4, 2, 5); 

Just one small thing: it'd be nice to have an example for cursor declaration with named parameters.  Your patch adds one for opening a cursor, but not for declaring one.

Other than that, I think the patch is good.  Everything works as advertised =)
