Issue 397

Details

Changes the regular expression used to recognize table name when doing simple SQL command parsing. Previously it looked for the first FROM but this was confused by subexpressions such as SUBSTRING('foo' FROM x TO y). This changes the code to look for the last FROM instead.

Looks good. The tests we have should protect us from most changes in behavior that our customers might see from this change. Still, it's not extremely low risk, so we should be ready to patch this back the way it was if it starts to cause problems.
