I believe this text is false on too many accounts. So, what's the consensus
about Inheritance in PostgreSQL, I am going to give a talk on it in November
and I wouldn't like to advertise/promote/teach something that the community has
decided to abandon or drop. Actually I proposed several topics and they chose
this one (Inheritance).
Is the topic literally table inheritance, or really table partitioning? Often, people
who are not deeply experienced with PostgreSQL will use the term "inheritance"
to mean table partitioning, since before version 10, inheritance was the only mechanism
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 to mention it's an obsolete way of
doing partitioning.
If they really did mean table inheritance, that's a pretty esoteric feature to focus on
at this point. I strongly suspect they meant partitioning, and are using the term
"inheritance" loosely.
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!
