Fixed issue of "drop table" scripts causing tests to fail in samples.  Only done for sqlfire and postgres.
I believe others that do not have the "if exists" statements in their drop tables scripts should be retested as
I have not had to do this on any other previous version.  Suspect that "continueOnError" default flag has somehow
gotten flipped.
Made changes to generate-sql.  Do not understand how we copy from
generated-sources to /src/main/resources but the generation has fixed
all of the same bugs that were manually fixed in /src/main/resources
including the preferred approach, drop contraints for postgresql.
Failed to add all of the files in the previous commit.  These are the
other additional changes made.
