Another way of dumping only the functions, based off the view pga_functions:

-- view definition
create or replace view pga_functions as
select
l.lanname as language,
n.nspname||'.'||p.proname||'('
||pg_catalog.oidvectortypes(p.proargtypes)||')' as name,
t.typname as returntype,
'\n\n'||'CREATE OR REPLACE FUNCTION
'||n.nspname||'.'||p.proname||'('||pg_catalog.oidvectortypes(p.proargtypes)||')\n'||
' RETURNS '||t.typname||' AS'||'\n''\n' ||(select case when lanname <> 'c'
then replace(prosrc,'\'','\\\'') else replace(prosrc,'\'','\\\'')||'.so'
end)||'\n''\n'||' LANGUAGE ''' || l.lanname || ''' VOLATILE;\n' as source
from pg_proc p, pg_type t, pg_namespace n, pg_language l
where p.prorettype = t.oid and p.pronamespace = n.oid
and p.prolang = l.oid;

dev=# select source from pga_functions where name like 'public%'
dev-# \o dump_all_functions.sql;

This will dump public's functions to a file. You may want to play with the
settings of view etc to get the formatted results you want.

Note: I did not create this view, I found it in the archives a while back, along
with pga_objects, pga_columns, and pga_views.

Cheers,
