Need some info on Postgresql

Hi Team,

I am using Postgresql 7.4.2 version on Solaris. There are number of tables say about 30+ tables in our database. I started to “reindex” the tables individually. “reindex table <<table name>>”. All the queries executed normally with less than 1 minute of duration. But one table is not responding any thing even after 10 minutes. The details of the table are …

1) it had 5 column, out of it, one is primary key.

2) There are only 5 rows in it.

3) see this entry for index on that table

                        Schema |           Name            | Type  | Owner |        Table

------------+------------------------------+---------+----------+----------------------

                        public | currency_pkey             | index | pgsql | currency

Can you please tell me why it not executing this command on the particular table and I am the owner of the DB? Can you please suggest some thing. We found these days, the database is taking more time to execute any query. We are doing “vacuum Verbose analyze” regularly at low traffic time.
