Here is a little PL/pgSQL sniplet, I used to delete all tables from
schema public:
----- snip-snap -----
CREATE OR REPLACE FUNCTION dropit() RETURNS integer AS'
DECLARE
numberoftables integer := 0;
tabletodrop RECORD;
BEGIN
FOR tabletodrop IN SELECT tablename from pg_tables where
schemaname=''public'' LOOP
numberoftables := numberoftables + 1;
RAISE NOTICE ''Droping table %'', tabletodrop.tablename;
EXECUTE ''DROP TABLE public.''
|| tabletodrop.tablename;
END LOOP;
RETURN numberoftables;
END;
' LANGUAGE plpgsql;
----- snip-snap -----
You execute it by "select dropit();" on the psql commandline.
But be warned, it will drop _all_ tables in the used schema.
