Hi there,
when creating a tablespace pointing to an existing directory, PG create a subderictory with this pattern :
PG_???_!!!!!!!!!
where ??? is the version (by instance 9.1)
but I don't know what is !!!!!!!!!, actually 201105231
I can imagine that is a build version, but how can I obtain this number by a SQL Query ?
Thats a system catalog version number. You can retrieve with pg_controldata
Eg:
-bash-4.1$ ./pg_controldata
pg_control version number: 903
Catalog version number: 201105231
Database system identifier: 5719586032196955957
Database cluster state: in production
