If i run:
pgbench -i -s30
And then create the function:
CREATE OR REPLACE FUNCTION foobar(text)
RETURNS text
LANGUAGE plperl
IMMUTABLE PARALLEL SAFE STRICT COST 10000
AS $function$
return scalar reverse($_[0]);
$function$;
Then when I create in index, I get a warning:
jjanes=# create index on pgbench_accounts (foobar(filler));
WARNING: cannot set parameters during a parallel operation
WARNING: cannot set parameters during a parallel operation
If I create the index again within the same session, there is no WARNING.
This only occurs if plperl.on_init is set in the postgresql.conf file. It doesn't seem to matter what it is set to,
even the empty string triggers the warning.
plperl.on_init=''
As far as I can tell the index is created correctly despite the warning.
Cheers,
Jeff
