Hi,
Just wondering if you'd like to write this up into an article for the
techdocs.postgresql.org site, as there is a decent level of interest in
moving from MS Access to PostgreSQL. There are a few documents around,
but nothing which mentions this from what I remember.
:-)
Regards and best wishes,
Justin Clift
