PostgreSQL doesn't have multiple editions in the way that some other database management systems (DBMS) might have (like Oracle with its Standard Edition, Enterprise Edition, etc.). Instead, PostgreSQL is released as a single open-source distribution with the same core features available to all users.
However, there can be different distributions or packages of PostgreSQL provided by various vendors or organizations that might include additional tools, extensions, or support services. Some of these distributions might have their own names, but they are typically built on the PostgreSQL open-source base.
Here are a few examples:
1. **Community PostgreSQL:**
- This is the standard open-source distribution available directly from the PostgreSQL Global Development Group. It is often referred to as "Community PostgreSQL" to distinguish it from other distributions.
2. **EnterpriseDB (EDB) PostgreSQL:**
- EnterpriseDB provides a distribution of PostgreSQL along with additional tools and services. Their distribution is often referred to as "EDB PostgreSQL."
3. **Postgres Plus Advanced Server:**
- This is another distribution by EnterpriseDB that includes additional enterprise-class features on top of PostgreSQL.
4. **Amazon Aurora with PostgreSQL compatibility:**
- Amazon Aurora is a managed database service by AWS, and it offers compatibility with PostgreSQL. While it's not a traditional distribution, it's worth mentioning as it provides a PostgreSQL-compatible environment with some AWS-specific enhancements.
