It means Postgres can do a reliable backup (a consistent snapshot) of a
database without shutting down the database.
What you are asking for is replication, which is not easy to implement,
and almost damn impossible to get it RIGHT. (*curse at both Sybase and
Oracle replication servers*). (i.e.
See archives of this mailing list.
WAL is write-ahead logging, more conventional way of assuring atomicity.
(I.E. before a transaction is written to database, it is written to
transaction log, which can be replayed). Replication can be achieved by
streaming transaction log toyour replicated compu

Yeah, openbsd ld/ld.so for example will bitch and moan when its asked to
do this. (nonPIC code loaded as so). So this is to be used as last resort.

Then you probably didn't install the binary shared library (Pg.so) to the

SETOF is to return more than one record, not more than one field. Also,
SETOF is only currently working for SQL language functions.

Here's the story about pgsql and jail:
1. FreeBSD shared memory is _really_ shared across all jail VMs. I think
its not going to change, as this seems like a great way for processes to

I guess they want to it with KOrbit, and some software translating
cobra->mysql (mysql doesn't have corba bindings yet, to my knowledge).
The same should be possible with postgres, and it actually DOES have corba
bindings (albeit they are broken AFA

Basically, answer is: you can't do it, no matter how you slice it, for a
simple reason: postgres doesn't support nested transactions [yet?].

A quick question:
Have someone made effort to do profiling of pgsql during execution of
certain things (inserts, selects, sorting, indices)?
I have a feeling (based on stopping postgres from gdb periodically), that
a lot of time is used in strcoll() (if table and index has string
columns).

If you are asking if WAL logs can be reapplied to an database dump, the

Not 'transaction'. If previous operation _failed_, you won't even get to

Hi,
I though that searches on a table based on oid should be very fast (select
* from table where oid=), however, this doesn't appear to be the case.
My assumption was that essentially, if there is no clustering on the
table, it is physically ordered by OID. Is that correct? Or vacuum may

I have a bit of a problem:
'select from xx where field=null' will always result in seq scan even when
there's a [btree] index on the field.

Hi,
Am I correct in impression that the only way you can store binary data
(meaning data that could have all control characters including \0 in it)
is using Large Objects interface? I have tried bytea and text, both
truncate string on receipt of \0...
Also, what's physical storage size of a LOB?
now() is a function, and you should use it as now()

Sounds like you are running of filedescriptors That can be due to
following factors:
1. Kernel limit is exhausted (not likely, i think default is
1024fds/process), and needs to be adjusted
2. You are exceeding your ulimit for fds. type ulimit -a and see what's it
set to.
3. Postgres is leaking FDs

Afaik, not possible, at least I couldn't get any \0s into bytea column
from psql nor from perl DBI interface. You need blobs if you want to store
data which contains embedded nulls. Or so I think.
