Re: How to delete all operators

Hi,

I have a database with operators and functions in plpgsql.
To update the data to the latest version I would like to drop all operators.
There might be some, that I don't know. I don't have access to the database,
but have to write a script, that will update the data.

Is there any way to drop all operators (given they are all in the schema
"public) in a script?

Something like (pseudocode):
Drop all operators in schema "public"

Thanks in advance for answers

You can make a function to do this.

CREATE FUNCTION drop_operators(text) RETURNS BOOL AS
$$
DECLARE
op record;
BEGIN
FOR op IN SELECT opname
FROM pg_operator as o left join pg_namespace as n on (
o.oprnamespace = n.oid)
WHERE nspname = $1
LOOP
EXECUTE 'DROP OPERATOR '||quote_literal(op.opname)||';';
END LOOP;
RETURN TRUE;
END;
$$ LANGUAGE 'plpgsql' IMMUTABLE;

And so: SELECT drop_operators('public');

Nope, though information_schema or the newsysviews project on
pgFoundry might make it easier to get that list of operators.
