Look in the $PGDATA/postgresql.conf file for a line like this:

#silent_mode = false

and change it to:

silent_mode = true

for most users the easiest way is with oid2name. run by itself it will
tell you the oids of all your databases:

oid2name
All databases:
---------------------------------
16976  = postgres
1      = template1
16975  = template0

with the -d switch it tells you all the oids of all the tables etc in that
database:

oid2name -d postgres
All tables from database "postgres":
---------------------------------
1172039 = accounts
1172041 = accounts_pkey
1401440 = b
1172031 = branches
1172033 = branches_pkey
1172043 = history
1401427 = k
1401425 = k_id_seq
16977  = rax
51531  = rax_corp_acct_id_dx
51532  = rax_cust_acct_id_dx
51534  = rax_cust_acct_name_dx
51533  = rax_order_item_renew_dx
51530  = rax_pri_acct_id_dx
1172035 = tellers
1172037 = tellers_pkey
1455938 = test
1455936 = test_id_seq

Since all the data for most postgresql databases sits in the $PGDATA/base
directory, you can find the size like this:

ls -l $PGDATA/base/dboid/fileoid

For the rax_corp_acct_id_dx in postgres database, it would be:

ls -l $PGDATA/base/16976/51531
-rw-------    1 postgres postgres  1105920 Mar 28 11:17
/mnt/d1/data/base/16976/51531

so that's about 1 meg.
