any caveat upgrading from 7.2.1 to 7.3.x on RH 7.3?

Hi all,


Any caveat upgrading from 7.2.1 to 7.3.x on RH 7.3?

Like for example:

pg_access, perl's DBI::pg, function and/or keyword no longer supported,
different behaviours, etc

I know about COPY not converting '' to 0, but what about the rest?

I am craving for SCHEMA...
