When deleting data from JDBC resource, driver class needs to be initialised in some circumstances

[pflooky]

From testing with Data Caterer example PostgresPlanRun, if you set the following plan flags after generating data:

val config = configuration
  .generatedReportsFolderPath("/opt/app/data/report")
  .enableUniqueCheck(true)
  .enableRecordTracking(true)
  .enableDeleteGeneratedRecords(true)
  .enableGenerateData(false)

You get error:
Caused by: java.sql.SQLException: No suitable driver found for jdbc:postgresql://host.docker.internal:5432/customer

A quick fix is to add this line of code: Class.forName("org.postgresql.Driver")
