are there some tool or internal program that read a dump file (created by
pg_dump) and list all tables and number of tuples (without
restore) in this file?
That command should give you the number of tables in your plain dump:
I have used EnterpriseDB's MigrationWizard to migrate a mysql database.
Everything went well except for:

It does not give me the $CLUSTER_NAME information.

cool actually.
any idea for the number of tuples?
count all lines after COPY .* ) FROM stdin;
until \.
(but how?)
on a side note: what's the difference between the admin list and the general

Your best bet would be to use whatever scripting language you like
which has decent support for regular expressions. Expect to tweak
your expressions a bit as you discover the corner cases where you're
not getting
Thanks Kevin. That confirms what I've seen on 8.3.
Could you explain what causes index bloat when running vacuum full? I've
read that index bloat can occur, but no quite sure what is going on internally.

To collapse the space, it copies tuples to locations closer to the
front of the table. The index needs to contain references to the
old and new tuple copies until the VACUUM FULL
That would explain it. I was neither in a transaction nor did any explicit
HOLD.
Thanks Kevin.

Hi All,
Is there an easy way to restore to a new table where the column name

Restore to the old name and then rename the column?
Access the backup file and change the COPY statement to the new
column name?

There are a couple of ways. Assuming that it's the same database, and it's up
and running, you could do this:
Assuming:
table foo (col1 text, col2 int);
table bar (col2 text, col3 int);
insert into bar (select * from foo);
would stick everything from foo.col1 and foo.col2 into bar.col2
Awesome, this will work. It won't retain the column name in insert
into statement. I was not sure if this will work with postgres 8.2.5 but
it does.
Thanks.

Hello, everybody
recently I have found that queries on our customer database take longer to
execute than normally.
First thing we did was to log long queries. This led to nothing as queries
logged are usually executed fast. On the other hand sometimes they take
considerable amount of time...

There can be a number of reasons. The time to transmit the query

Dear all
the situation is that: I have a table, and the size is about 10M, I run the
database on Redhat Linux platform. for OS, a IO can hand 1M data, the file
system block is 4k, database block is 8k,
my question is that: when do the full table scan on the table, how many IO
will be done?
