Based on notes from the PostgreSQL development team and subsequent
testing on our machines, it appears this issue was fixed by either
6.5.2 or 6.5.3 - so the pipe above should work reliably now, assuming
your view was created using a DBMS version 6.5.3 (or maybe 6.5.2 will
do as well). To avoid needing to destory/create the DB, use:
pg_dump -c -o -h <live> <database> | psql -h <mirror> <database>
Note the addition of the -c option and the correction of my typo --
where I meant <database> I said <table> earlier.
Hope this helps.
