PostgreSQL with different data directories

Question

Today I installed PostgreSQL to work with. When I was reading the documentation, I found there can be more than one data directory present. Is it more than one data directory for single installation ? Or I understood wrongly ?

In my installation, data directory is in

C:\Program Files\PostgreSQL\8.3\data

if it can be more than one data directory for single installation, how will be the directory structure ?

Answer 1

I think you mean a tablespace, please check the manual: CREATE TABLESPACE
