I do like Kevin's solution of using the pg_table_is_visible() function - I  
think it
was me that last altered that section of code and I must admit it's the  
first time
I've come across this function.

There is no need to complicate things further by adding a plpgsql wrapper  
though -
simply alter the SQL queries used in the C code, as the majority of the  
work is done
by passing SQL query strings to the SPI directly anyway.


ATB,

Mark.
