James,
Depends what you are doing. We have been using mostly Access 2003/2000,
but I presume it works just as well with Access 2007.
You can migrate the tables by doing simple export table individually to
a PostgreSQL ODBC source or use Ogr2OGr to do a bulk multi-table dump
and just drop the geometry table it creates for each table. Then just
relink the tables as linked tables.
You can rewrite the queries as views or just keep them as queries.
Reports can not be exported because they aren't really database objects
as far as PostgreSQL and SQL Server are concerned.
Many of our applications have MS Access as the front end and PostgreSQL
or SQL Server or combination of both as the back end and its a fairly
nice combination. If you don't have any qualms with keeping your Access
front-end, that tends to be
the easiest route to go.
Below is are some articles you may find useful that covers some gotchas
and load examples

Unfortunately using PostGIS from within MS Access is a little trickier.
For simple spatial queries - e.g. distance queries that just return
attribute data, I use MS Access pass-thru queries.
There is also MapWindow if you need to display maps - but haven't had
much success getting it to work last I tried which was about a year or
so ago. The PostGIS driver for it still seems very low alpha quality,
but it may be worth a try if
you need to show your maps from within MS Access.

Hope that helps,
Regina

Subject: [postgis-users] MS Access to PostgreSQL
Hi all,
I am a bit of a newcomer to PostGIS and wanted to ask a question.
Is it possible to migrate a database from MS Access into PostgreSQL? Can
table structures, queries, rules, indexes and reports be moved over
easily or is it a case of having to recreate everything by hand?
I am using Access 2007.
We would then like to extend the attribute data by adding spatial
information to the records as well.
Many thanks,
James
