So this is a psql bug? I can count the correct number of chars with
SPI:
alvherre=# create or replace function factorial_length(int) returns int language plphp
alvherre-# as $$ $r = spi_exec("select factorial($args[0])");
alvherre$# $row = spi_fetch_row($r);
alvherre$# return strlen($row['factorial']); $$;
alvherre=# select factorial_length(4000);
factorial_length
------------------
12674
(1 fila)
alvherre=# select factorial_length(6000);
factorial_length
------------------
20066
(1 fila)
