There has been a change in function names in the new RMySQL 0.5-0
version (also in the new ROracle and RSQLite).  The reason is that
the R-SIG-DB has agreed on a common interface to all databases,
and as part of this new common interface, most functions have been
renamed.  The following simple name mapping may help you upgrade
existing code to the new DBI:
