You don't keep the SQL for your functions in
source code control?
When working on a database design, always keep your
original *and* modified SQL scripts so that you can
always create an empty version of your production
system. Part of that is creating drop scripts
for each object, including functions, that you create.
CYA.
For those of you playing fast and loose,
this query will produce a list of functions and arguments
in the schema public. Use it in a shell script loop
to drop your functions.
SELECT
n.nspname || '.' || p.proname || '(' || pg_catalog.oidvectortypes(p.proargtypes) || ')'
FROM pg_catalog.pg_proc p
LEFT JOIN pg_catalog.pg_namespace n ON n.oid = p.pronamespace
WHERE p.prorettype <> 'pg_catalog.cstring'::pg_catalog.regtype
AND p.proargtypes[0] <> 'pg_catalog.cstring'::pg_catalog.regtype
AND NOT p.proisagg
AND n.nspname ~ '^public$';
DO NOT under ANY circumstances drop
ANY functions in the schema pg_catalog.
