FLDP/HVR currently misses the AdaptDDL/Schema Evolution for PostgreSQL sources. This turns out to be a big limitation for our internal sources as most of our planned future sources are on PostgreSQL and looking for this feature. One of the source opted out of HVR because of this limitation which is not a good news. Currently, there are options to manually support DDL changes but these don't suit our requirements and we're keenly looking for AdaptDDL feature like the way it is supported on other DBs.
