Is there any way to programmatically determine the last committed
transaction in the database. If this is possible, what information is
available?

The only thing I can think of is to run CHECKPOINT then look at
pg_controldata.  Another idea is to insert into a table, then look at
that rows xmin values to see the transaction id.
