Hi.
A few days ago i've installed PostgreSQL 7.4.1
After the installation, Postgres was very fast.
But now, a few days later, it getting slower and slower.
1. Is the database designed well? For example: did you create indices
on fields used as search keys, ecc...
2. Do you vacuum you database once in a while? look for "vacuum
in the manual"...
I've looked in the data-dir and i was confused when i see the big
size from that directory.
A dump (created with pg_dump) is about 1MB.
pauli# cd /usr/local/pgsql/data
epauli# du -h
4.4M ./base/1
the template database is about 4MB
4.4M ./base/17141
19M ./base/17142
this is your database
i'll be more than 1 MB due to: not reclaimed free space (vacuum!), index
lookup tables, various overhead, ...
4.4M ./base/17143
4.4M ./base/17149
4.4M ./base/17158
4.5M ./base/29156
4.4M ./base/29175
4.5M ./base/29184
there are a few empty or almost empty databases;
see what they are with psql -l
55M ./base
160K ./global
32M ./pg_xlog
98K ./pg_clog
the transaction log files - always there after first use;
don't touch them, you'll need them!
Bye, Chris.
87M .
Does anybody know why this directory is 87MB while the database is
1MB?
