This is what I'm trying to do, but it's a total nightmare..
First, I did a:
pg_dump -U root MyDB > c:\DB.dbs.out
which appears to have worked.. Then, I edited the file in Notepad and
saved it as UTF8 which also appears to have worked. Next, I created
the new DB using UTF8, and ran:
psql -U root MyDB2 < c:\DB.dbs.out
I get pages and pages of errors about foreign key restraint violations
and other stuff. Looking at the DB after, almost all tables are
empty. When I look at the DB.dbs.out file more carefully, the problem
is fairly obvious. It attempts to create all the tables in
alphabetical order. First, it inserts data into the "A" table which
has a FK restraint on the B table which isn't populated yet.
Obviously, this is going to cause problems. Perhaps when restoring a
DB you're supposed to drop all restraints first? I suppose I could
hack this into working eventually, but I was hoping there was an
easier way.. Thanks..
