withPostgreSQL will use the term "inheritance" to mean table partitioning, since before version 10, inheritance was the
onlymechanism for doing partitioning.  If what they really mean is partitioning, then you should focus on declarative
partitioning(the newer scheme introduced in version 10), and if you mention table inheritance at all, it should be just
tomention it's an obsolete way of doing partitioning.

Hello Christophe, they mean inheritance on the data design.  They wont 
be pgsql ppl, but mysql, mongodb in their majority I suspect, so they 
want to hear where PgSQL can have an advantage in the enterprise.

There are many blogs from top PgSQL companies (cybertec, percona, etc) 
who have praised inheritance at some point. For me (segregation , 
re-consolidation, look at the data from the POV of one subsidiary, then 
the next, then the top parent company is hard to live without )

Thank you!
