I see three choices:
1) On connection do
select set_config('search_path', 'test, ' ||
current_setting('search_path'), 'f');
with 't' to restrict to the transaction or with 'f' to restrict to session.
2) Include the search_path reset inside each function.
Or use the SET configuration_parameter { TO value | = value | FROM
CURRENT } to CREATE FUNCTION per:
https://www.postgresql.org/docs/current/sql-createfunction.html
3) If all this is being done by one role and for this purpose only then
from here:
https://www.postgresql.org/docs/current/sql-alterrole.html
ALTER ROLE { role_specification | ALL } [ IN DATABASE database_name ]
SET configuration_parameter { TO | = } { value | DEFAULT }
Be sure and read the complete docs for the caveats.
