Обсуждение: Private functions

Hi all,
is there a way to write a function that can only be called by another 
function but not directly using SELECT function_name ( )?
Thanks

Hello

directly no. There is only workaround - you can verify inside in
function content of pg_stat_activity_table - but this have to have a
superuser rights.
