Is
this a common issue among all RDBMSs or is it
something that is PostgreSQL specific?
Speaking from experience, this sort of thing affects MSSQL as well, although
the maintenance routines are different.
Yes, this is true with MSSQL too, however sql server implements a defrag
index
*statistics target = 100
*INFO: index timeseries_tsid now contains *16,677,521* row versions
in 145605 pages
DETAIL: 76109 index pages have been deleted, 2 are currently reusable.
CPU 12.00s/2.83u sec elapsed 171.26 sec.
INFO: timeseries: found 0 removable, 16677521 nonremovable row
Hi Tom,
I don't believe I did run Analyze, I was under the assumption that the
statistics would have been up to date when the indexes were created.
Thanks for the quick response.

I just restored a database running on a solaris box to a linux box

twice the memory allocated to postgresql, is there anything obvious that
I should look at? It is using a journal file system.
