Update of /home/cvsd/slony1/slony1-engine/tests/testinherit
In directory main.slony.info:/tmp/cvs-serv24546

Modified Files:
	README generate_dml.sh 
Log Message:
Modify "testinherit" test to add in a test of subtransactions/savepoints.

- A bunch of concurrent psql sessions generate random lists of regions/products
  - each of them performs purchase transactions based on these lists
  - some of the purchases get rolled back
  - some "sleep" requests go in in order to increase concurrency

+ 
+ This test also performs a subtransaction test; it generates 16
+ more-or-less concurrent psql sessions that:
+  - create lists of products/regions (randomly, in temp tables local to each session)
+  - performs purchases on elements of those lists
+  - some of those purchases get rolled back, others don't
