Hi Sean,
Yeah - It is declared VOLATILE. I think there must be something specific with
the way PL/PGSQL handles child processes of a called function. The child
process actually spawns mpg123 or ogg123 so it has to live beyond the life of
the parent. Not sure. What I might do is rewrite the entire procedure from
woe to go in using SPI and see how that goes. Failing that I guess I could
always peek at the source! : )
Thanks,
Jason
