Tom is right, you need plperlu if you want to do this. Or be more careful
in your function by (for example) querying the pg_class table to see if
the table exists. Another alternative is to have pl/perlu do all the
"heavy lifting", and make some more limited wrapper functions in pl/perl.
And for the sake of the archives, it is "spi_exec_query" not "spi_query_exec".
