I assume that by transaction you mean record I assume that you are using serial or big serial as
the autonumber for your new postgresql tables.

1) you need to determine the table_sequence name that was created for you table.
2) change the table_sequence value to one greater than the values already stored in the table from
access.

The function you need it setval()
http://www.postgresql.org/docs/8.2/interactive/functions-sequence.html

you can use setval() useing the psql client utility to postgresql.
