Any help in getting function argument names is appreciated. Thank you
To dump the functions and their definitions , I first created a
pga_functions view as mentioned in one of the archives.
First Step: Create a pga_functions view
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,
E'\n\n'||'CREATE OR REPLACE FUNCTION
'||n.nspname||'.'||p.proname||'('||pg_catalog.oidvectortypes(p.proargtyp
es)||E')\n'||' RETURNS '||t.typname||' AS'||E'\n$$' ||prosrc
/* (select case when lanname <> 'c'
then replace(prosrc,''',''') else replace(prosrc,''',''')||'.so'
end)*/||E'\n$$'||' LANGUAGE ''' || l.lanname || E''' 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;
Second Step: Did a select from this view and dumped to a sql file
psql -d DATABASENAME -c "select source from pga_functions where name
like 'om%'"> omsfunctions.sql
Now in the file , not sure how to get the functions with argname or (not
sure if it's called the proargname)
Eg The original function is defined as
-- Function: oms.om_change_i_division(integer, text, text)
-- DROP FUNCTION oms.om_change_i_division(integer, text, text);
CREATE OR REPLACE FUNCTION oms.om_change_i_division(v_incidentid
integer, v_division text, v_olddivision text)
RETURNS void AS
$BODY$
DECLARE
v_Value TEXT;
v_OldValue TEXT;
v_Message TEXT;
BEGIN
v_Value := SUBSTR(v_Division,1,3);
v_OldValue := SUBSTR(v_OldDivision,1,3);
v_Message := 'Changed Incident Division to ' || coalesce(v_Value,'')
|| ' from ' || coalesce(v_OldValue,'');
update OM_Incidents
set
Division = v_Division
where
IncidentId = v_IncidentId;
PERFORM om_ins_audit(v_IncidentId,'Modified',v_Message);
RETURN;
END; $BODY$
LANGUAGE plpgsql VOLATILE
COST 100;
ALTER FUNCTION oms.om_change_i_division(integer, text, text) OWNER TO
oru;
The output of a function with the above pg_functions view comes out as
below with no argument names.
-- Function: oms.om_change_i_division(integer, text, text)
-- DROP FUNCTION oms.om_change_i_division(integer, text, text);
CREATE OR REPLACE FUNCTION oms.om_change_i_division( integer, text,
text) (With no argument names)
RETURNS void AS
$BODY$
DECLARE
v_Value TEXT;
v_OldValue TEXT;
v_Message TEXT;
BEGIN
v_Value := SUBSTR(v_Division,1,3);
v_OldValue := SUBSTR(v_OldDivision,1,3);
v_Message := 'Changed Incident Division to ' || coalesce(v_Value,'')
|| ' from ' || coalesce(v_OldValue,'');
update OM_Incidents
set
Division = v_Division
where
IncidentId = v_IncidentId;
PERFORM om_ins_audit(v_IncidentId,'Modified',v_Message);
RETURN;
END; $BODY$
LANGUAGE plpgsql VOLATILE
COST 100;
ALTER FUNCTION oms.om_change_i_division(integer, text, text) OWNER TO
oru;

One more thing you can also get it from pg_get_functiondef() system
function.

You have two options.
* Use contrib module pg_extractor
https://github.com/omniti-labs/pg_extractor
* Use pg_proc catalog to get function definition

Hello all- Is there a way to just dump functions in a schema in to a
txt file/ sql file ? Thank you.
