Yes I have and I believe I understand how to use pg_dump for the most
part. The last time I used pg_dump and pg_restore to create a new
database. The procedure went something like this:
1) pg_dump
2) psql create database testdb
3) pg_restore
This seems to have the affect of keeping OIDs. Are OIDs universal to an
installation or specific to a database? I thought that when I created
the new database the OIDs would start over at 0 but they didn't appear
to do so. I will check later but I am not sure whether or not the
sequences were reset to 1 or not either. My desire is to simply create
a clean database. I have read about OID counter wraparound and how that
can be bad but I do not yet understand the implications of this issue.

I suspect that I need to use pg_dump to output the SQL commands
necessary to create the data dictionary and then run these commands via
psql. Do I just cat the file into psql? i.e. cat data_dictionary.sql
> psql -database NEWDB -username postgres
