Re: Deleting Functions

Scott,

I use the following query with psql \o option. Change the schema name from public to whatever. I am sure you could put
this into a plpgsql function using execute as well.

Jim

\o drops.sql
select 'drop function ' || nspname || '.' || proname || '(' || pg_catalog.oidvectortypes(p.proargtypes) || ');' from
pg_proc p join pg_namespace b on (p.pronamespace=b.oid) where nspname='public';
\o
\!vi drops.sql # <<remove the fluff from the query
\i drops.sql
