I'm working on a function that will return a set of test data, for unit
testing database stuff. It does a few things, but ultimately returns
SETOF record that's essentially:
RETURN QUERY EXECUTE 'SELECT * FROM ' || table_name;
Because it's always going to return a real relation, I'd like to be able
to the equivalent of:
SELECT ... FROM my_function( 'some_table' )::some_table;
Is there any trick that would allow that to work? I know that instead of
'SELECT * ...' I can do 'SELECT row(t.*) FROM ' || table_name || ' AS t'
and then do
SELECT ... FROM my_function( 'some_table' ) AS data( d some_table )
but I'm hoping to avoid the extra level of indirection.
