Hi,
I need to execute the INSERT statement on the table having NUMERIC

I know that is possible via
EXPLAIN and EXPLAIN ANALYZE
to get planned and actual time for one query - but no results.
I am looking for information like:
to do this query, I had to:
- read x units from disk/os.cache
- get n units from my own buffers
- do n1 comparisons of strings
- do n2

I don't think that cast isn't doing what you expect at all. As an
example, try doing something like:
select cast(bytea e'hi\nbye' as varchar);
encode() may be what you want
So the query is:
SELECT m.messageid, mad.destination
FROM messages AS m
LEFT JOIN message_address_link AS mal ON (mal.message_id =
m.messageid)

WHERE delete_status 1

Hi Scott!
The problem is that my test database has several tables with many links between
them, so I have no idea which 1000 rows to get from which table. The only thing
I can do is run the program that connects to that database and tell it to run
on a sample of the database.

Hi All,
While recovering a database, we encountered a file permissions problem on new
WAL segments that caused recovery with pg_standby to exit prematurely. Now the
database is in a new timeline. What we need to do (I think) is reset the
database timeline to that of the base copy and resume

Failing anything else, there's always direct UPDATE of the pg_constraint

If it's only a matter of the entry in the pg_constraint catalog being

Numeric is definitely what you want. You probably want at least four
fractional digits, since sales tax (at least in California) is
routinely set to a quarter of a point. For example, the

Oops sorry I was thinking 2,3 meant 2 significant digits to the left
of the decimal point and 3 to the right. I just re-read the docs and
now see what you mean. 6,3 would work fine though is maybe a bit
overkill since a 100% sales tax rate would cause a violent revolution
