Is there any way of determining the actual structure of a record variable? E. g. I've written a small script to do some calculations over some fields with a dinamically generated query. It looks like this:
create function foo(text) returns void as $$ declare a_record record; my_query alias for $1; begin for a_record in execute my_query loop -- Do some calculations end loop; return; end; $$ language plpgsql;
The question is: how could I possibly get the field names and other information about the record a_record? I appreciate any suggestions or tips about this.
