=================

PGD compatibility with Postgres versions
----------------------------------------

The following table shows the minimum minor version, per major version,
that EDB Postgres Distributed (PGD) 6 is compatible with, across
Postgres, EDB Postgres Extended (PGE), and EDB Postgres Advanced Server
(EPAS).

..  Important::
   PGD 6.5.0 and later require EDB Postgres Extended 18.6.0 or later. PGD 6.0 through 6.4 aren't compatible with EDB Postgres Extended 18.6.0 or later and must stay on EDB Postgres Extended 18.1.0 through 18.5.x. If you're running Postgres 18, upgrade PGD and EDB Postgres Extended together to avoid landing on an unsupported combination.

EDB recommends that you use the latest minor version of any Postgres
major version with a supported PGD.
