## selectWhereZero test
##
## test for the 'Issue 1' on the Google Code issue log
## this was reported in June and fixed by Joe Conway (svr committ r100)
##
## Assumes that
## a) PostgreSQL is running, and
## b) the current user can connect
## both of which are not viable for release but suitable while we test
##
## Dirk Eddelbuettel, 03 Oct 2009
## only run this if this env.var is set correctly
if (Sys.getenv("POSTGRES_USER") != "" & Sys.getenv("POSTGRES_HOST") != "" & Sys.getenv("POSTGRES_DATABASE") != "") {
## try to load our module and abort if this fails

## connect to the default db
