Hi:
I'm trying to justify disk space for a new linux server they're going to give
me for my Postgres instance. When I do a "du" of the place I installed the
older instance on the system that is to be replaced, I see that the vast, vast
majorityof the space goes to the contents of the "base" dir. In there are a
bunch of files with integers for names (iod's ?). And some of those have
millions of files inside.
Is this normal? Should there be millions of files in some of these "base"
directories?
Is this indicative of some sort of problem or lack of cleanup that I should
have been doing?
The "du" shows that I'm using 196G (again, mostly in "base") but
pg_database_size shows something like 1/4 that amount, around 50G. I'd like to
know if there's something I'm supposed to be doing to cleanup old (possibly
deleted) data.
Also, I was running pg_size_pretty(pg_database_size('mydb')) on all the dbs.
It runs very fast for most, but just hangs for two of the databases. Is this
indicative of some sort of problem? (BTW, the 2 it hangs on are very much like
others that it doesn't hang on, so I used those numbers to estimate the 50G)
Thanks in Advance.
