Thanks Adrian Klaver,
Provided link gives about the information of what PG_VERSION file, which am aware of:)
In my observation, all the object related OID's, _fsm, _vm files under $PGDATA/base/database-oid/ directory will change as per the changes made to the database, whereas PG_VERSION file never changes. Because its the file tells on which version of Binary the Data directory is built upon.
So, my question is, Is there any case, where PG_VERSION file updates with any of the utility process or
PG_VERSION file never been touched by PG-Instance ?
