Difference between Base Directory and Global Directory
In PostgreSQL, both the Base Directory and the Global Directory reside within the PGDATA (the data cluster) folder. The primary difference lies in the scope and type of data they store.

1. The Global Directory (pg_global)
The global directory contains data that is shared across the entire database cluster.
- Path:
$PGDATA/global/ - Scope: Cluster-wide.
- Contents: It stores “Shared System Catalogs.” These are tables that contain information applicable to every database in the instance.
- Key Files:
pg_database: Information about all databases in the cluster.pg_authid: User roles and passwords (since a user can log into any database in the cluster).pg_tablespace: Information about defined storage locations.
- Identification: Objects in this directory always have an OID (Object Identifier), but they do not belong to a specific database ID.
Lists only actual shared/global catalog tables (no indexes, no TOAST tables) from the global directory

2. The Base Directory (pg_base)
The base directory contains the actual user data and system catalogs that are private to each specific database.
- Path:
$PGDATA/base/ - Scope: Database-specific.
- Structure: Inside
base, there is a subdirectory for every database in the cluster, named after the database’s OID (e.g.,$PGDATA/base/16384/). - Contents:
- User Tables and Indexes: The actual data you insert into your tables.
- Local System Catalogs: Tables like
pg_class,pg_attribute, andpg_typewhich describe the structure of that specific database.
- Identification: If you want to find where a specific table is stored, you look in
base/[Database OID]/[Table Filenode]
