Update of /home/cvsd/slony1/slony1-engine/tests
In directory main.slony.info:/tmp/cvs-serv17611

Modified Files:
	support_funcs.sh 
Log Message:
Fix usability of C-based random data generators:

1.  Change existence test to use -x (is program executable) rather than -e
    (merely checking for existence)

2.  Typo in string handling was throwing away string values when we ran
    the C-based "random_string" program
