If by "debug version" we mean a version compiled with -g, it will
be fine.  It shouldn't affect performance at all. All it will do
is make the binary bigger on the disk (not in memory) and make it
take longer to compile.

This server runs ten thousand queries per day? This is a very low
volume of queries, so unless the queries are hideously complex,
you shouldn't need to worry about performance.

86,400 seconds per day / 10,000 queries works out to one query
every 8.64 seconds. Of course the load will not be perfectly even,
but even so I doubt you'll be seeing a short-term average of more
than one query every two seconds. I recommend you use at least a
386SX-16 system for this. :-)

BTW, there are tools like "top" and "iostat" that can tell you how
loaded your system is. Or you an probably even just look at the
disk lights.
