Hi,
In my liquibase.properties I have specified:
diffTypes: index (not indexes as specified here: http://www.liquibase.org/documentation/diff.html)
The operation takes a lot of time and if I have a look at the log file it seems like the option is ignored:
select ucc.column_name from all_cons_columns ucc where ucc.constraint_name='my_table and ucc.owner='owner' order by ucc.position
