However, that objection doesn't hold for plperl or pltcl (and likely
not plpython, though I don't know that language enough to be sure).
So it would be a reasonable feature request to teach those PLs to
accept "record" parameters. I think the fact that they don't stems
mostly from nobody having revisited their design since the
infrastructure that supports record_out was created.
That seems like a good idea. I'll look at it for plperl.
A naive implementation turns out to be really trivial. It's about two
lines, and we can then do:
andrew=# create function rfunc (x record) returns text language
plperlu as $$ use Data::Dumper; return Dumper(shift); $$;
CREATE FUNCTION
andrew=# select rfunc(row(c.relname,n.nspname)) from pg_class c join
pg_namespace n on c.relnamespace = n.oid limit 1;
rfunc
--------------------------------------
$VAR1 = '(pg_statistic,pg_catalog)';+
But I think we can do better than this. We should really pass an hashref
with the record's column names as keys rather than just calling
record_out. I'll work on that.
