I have the same postgresql databases on two different servers.
Boteh servers have the same version of postgresql, 8.1.
The following backup command creates a file twice as big on one server, compared to the other server.
pg_dumpall -c -U postgres | gzip > alldb.gz

Red Hat 5EL: alldb.gz is 29MB
Fedora Core 5: alldb.gz is only 15MB

Any ideas as to why the red hat box pg_dumpall file is about twice the size?

Marc
