PostgreSQL: What is data replication? I read from a post about comparing MySQL and PostgreSQL, there is one who said:


  The biggest disadvantage of PG for me had been the lack of
  replication, but it's recently gotten both asynchronous and
  synchronous replication.

So my question is: What does that "PostgreSQL lacks replication" mean?
It means nothing, really. PostgreSQL has a number of replication features, as the relevant chapter in the manual details.

That article is apallingly wrong and outdated. Ignore it. "No referential integrity" in MySQL? Bah.

If you have an account on that site, please ask for it to be removed or fixed or whatever can be done. As it stands it's dangerously misleading and wrong, and has no place claiming to be current accurate information.
