when database exception happen on checkTableSequences next activity like checkTableID checkClientSequences will alway get error because transaction already broken.
so better do a logic, if exception happen and current database is postgresql will reset transaction
== test case ==
1. on window "Table and Column" duplicate record of "A_Asset"
2. on field "DB Table Name" change A to lower case
3. run "Sequence Check" process
4. get error message "** org.postgresql.util.PSQLException: ERROR: current transaction is aborted, commands ignored until end of transaction block"
