Re: Creating new database

I'dd suggest:

pgdumpall --clean > dump.sql

edit the dump.sql file by hand replacing database name and owners and
so...

then reload into the new DB with psql -f dump.sql postgres

this does all the work except creation of users and databases

should give you an exact replica with all data inside

see "man pgdumpall"
