Hi all,
 
can somebody explain to me, or point to an explanation of, the way, PostGreSQL names databases?I have files like 18732 and 7503034 - and they are big but I have no idea which data lives in what file:
 
/home/pgsql/data/base/18720/
-rw-------    1 postgres postgres 70385664 May 24 13:55 7503034
-rw-------    1 postgres postgres 10788864 May 24 13:54 8748869
-rw-------    1 postgres postgres   458752 May 24 12:21 8939786
-rw-------    1 postgres postgres 158334976 May 24 13:51 8945104
 
Best regards,
Chris
