Hey Vijaykumar,

Thank you for the quick response.

 

Q) do you see the functions expected to be dumped under \df public.* of the db ? 

Response) Yes, I do see all the functions listed.

 

However, when tried to dump it does not include all functions.

SET statement_timeout = 0;

SET lock_timeout = 0;

SET client_encoding = 'UTF8';

SELECT pg_catalog.set_config('search_path', '', false);

SET check_function_bodies = false;

SET xmloption = content;

SET client_min_messages = warning;

SET row_security = off;

I know in the public schema of the Tenant database there are over 60 functions and are not backed up. Any pointers are greatly helpful.

 

 

dumping only objects in a specific schema, also dumped functions in that schema, at least in my demo run.

 

postgres@db:~/playground$ psql test

psql (14beta1)

Type "help" for help.

 

test=# \df

                                              List of functions

 Schema |          Name           |     Result data type     |           Argument data types           | Type

--------+-------------------------+--------------------------+-----------------------------------------+------

 public | get_rounded_up_interval | timestamp with time zone | ts timestamp with time zone, i interval | func

(1 row)

 

test=# \q

postgres@db:~/playground$ pg_dump -n public test > /tmp/test.sql

postgres@db:~/playground$ grep -A5 get_rounded_up_interval /tmp/test.sql

-- Name: get_rounded_up_interval(timestamp with time zone, interval); Type: FUNCTION; Schema: public; Owner: postgres

--

 

CREATE FUNCTION public.get_rounded_up_interval(ts timestamp with time zone, i interval) RETURNS timestamp with time zone

    LANGUAGE plpgsql

    AS $$

begin

return  date_bin(i, ts, date_trunc('day', ts)) + i;

end; $$;

--

ALTER FUNCTION public.get_rounded_up_interval(ts timestamp with time zone, i interval) OWNER TO postgres;

 

***********

 I also tried using -Fd and then checked via. i do see functions dumped.

 

pg_dump  -Fd  -d test -n public -f /tmp/test.dump 

pg_restore -l /tmp/test.dump | grep -i function

219; 1255 72283 FUNCTION public get_rounded_up_interval(timestamp with time zone, interval) postgres

 

do you see the functions expected to be dumped under \df public.* of the db ?
