I always have a small wrapper function that builds my queries for me.
Assuming you have a list of values and their types (or a list of
structures)...
1. Build a list of comma-separated qmarks: join(',', map {'?'} @params)
2. loop through your params looking up the corresponding pg_type for
your internal type - bind the param accordingly
3. execute
Or am I missing something here?
