Re: Delete subset of database

Hi!

What about this?
(dirty hack, but worx)
----

#!/bin/bash
#sorry for syntax failures

tables_to_drop=`psql olddb -c "select * from pg_class where relkind =
'r' and name not like 'pg_%'"`;

for i in $tables_to_drop; do
    psql newdb -c "drop table $i ";
done;

----

Of course it is very risky, so first do it on your test environment.
