Postgres physical directory structure meaning
I want to know about the meaning of various directory present in data
folder. Mostly what will the 'base' folder contains? The reason of this is
recently in the datafolder 'global' was deleted unknowingly which leads to
entire DB crash in a second. We found a tool to get the data from the base
folder as sql queries, but many table content are missing.
Pls tell what kind of data will be present in each folder, if possible sent
the doc link.

"global" contains some system catalogs. Not terribly critical, but you
need to do quite some work in order to make the system work again
without them.

Yea, "base" was chosen because that makes the directory hierarchy
"/data/base", e.g. "database".
