Thanks for the reply anyway, it's a pity though, it'd be useful..

Another bump I've found along the pl/python road: insert ROWTYPE in table..
Maybe you have some hint on that? :)

So, in PLPGSQL I can:

DECLARE
  my_var my_table;
BEGIN
  my_var.col1 := 'asd';
  INSERT INTO my_table VALUES(my_table.*);
END;

How would I do something like that in pl/python?

First, how to declare a ROW-TYPE variable, as they're all python mappings?

my_var = { 'col1': 'asd' } enough? it'd would miss all the other columns...

Second, how to insert it?

plpy.prepare and .execute say they don't support composite types, so I cannot simply pass

pl = plpy.prepare('INSERT INTO core_customer VALUES ($1)', ['my_table'])

Any workarounds for this? (meaning I wouldn't have to specify any columns in the insert statement)

Thanks

PL/Python doesn't support that. Some more code needs to be written to support that. You did everything correctly. I don't know of a good workaround.
