AFAIC, PostgreSQL uses partitoned database files to store data. Thus,
it's far from MS Access' concept. (Furthermore, both method have its
own pros and cons.) But, in the related documentation (which I pasted
above), you'll see how easy it is to backup/restore a PostgreSQL
database/table/object using supplied utilities.

Hi,

With Pg you do not move a db file or files, but a dump file that has the data
in it.

You need to set up a Pg-system on the other machine, take a db dump on machine
1, move that file to the other machine and read it in.

E.g. / guide lines:

Machine1#pg_dump -c yourdb > yourdb_dumpfile

Machine2#createdb yourdb
Machine2#psql yourdb < yourdb_dumpfile

This moves one database.

To move all databases use pg_dumpall:

Machine1#pg_dumpall -c > all_dumpfile

Machine2#psql < all_dumpfile
