FUNCTION, TRIGGER and best practices

Hi All,

I have a function/trigger pair operating that move data from one table to
another after that data is inserted into the first table.

Can triggers and functions have the same name?
Is this a good practice?
Where should the function and trigger be stored?
In the same schema as the table they are connected to?

I will now be attempting to expand this function to move data from two source
tables to four or more target tables. (Different source columns go to
different tables.) Is it possible to do a transaction/commit/rollback inside
a function that is driven by a trigger so that if any portion of the transfer
fails it is all rolled back?

Thanks to all on this list that have helped me get this far. :-)

Kind Regards,
Keith
