Drop all databases objects except the database

Probably the fastest way is to drop the database and then
recreate... But if this doesn't suit then consider the (horrid) script
fragment below:

 psql -U sprint -A -q -t -c "SELECT relname FROM pg_class WHERE relname NOT LIKE 'pg_%' AND reltype != 0;" $1 | awk
'BEGIN{print "BEGIN;"} {print "GRANT ALL PRIVILEGES ON "$1" TO PUBLIC;"} END {print "COMMIT;"}' | psql -q $1 

I use this in a script to GRANT PUBLIC access to all tables in a
database. You could use something similar to DROP objects. Obviously
you'd need to get all tables from pg_class and DROP TABLE then, then
get all triggers DROP TRIGGER, and so on... See the follow page for
info on the pg_class table:

 http://www.us.postgresql.org/users-lounge/docs/7.2/postgres/catalog-pg-class.html

So in short... "dropdb db; createdb test"!!!
