If so, we know the problem is in this area (though still not exactly which reason); if not we need another idea. That's not a good permanent fix though, since it reduces crash safety. The other knobs to experiment with are synchronous_commit and wal_sync_method. If the stalls are due to commits waiting for additional xlog to get written, then async commit should stop them. I'm not sure if changing wal_sync_method can help, but it'd be worth experimenting with. All of my testing to date has been done with synchronous_commit=off I just tried setting full_page_writes=off - and like magic, the entire hiccup went away. OK, that seems clear. I mistakenly referred to the CRC calculation happening while the lock was held, which confused the discussion. The lock *is* held for longer when we have backup blocks and the lock does need to be acquired twice immediately after a checkpoint. Neither of the above two effects appear, on their own, sufficient to explain the delay. We should conjecture that a traffic jam exists and go looking for it. Propose a DTrace probe immediately after the goto begin at line 740 of xlog.c, so we can start tracing from the first backend following checkpoint, and turn off tracing when all backends have completed a transaction. -- Simon Riggs www.2ndQuadrant.com PostgreSQL Training, Services and Support -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

Re: [GENERAL] SPI_ERROR_CONNECT within pl/pgsql, PG 8.4
2009/7/13 Tom Lane t...@sss.pgh.pa.us: No, you're misinterpreting the message. What that code likely means is that something is trying to use SPI and finding plpgsql already connected. In other words, plpgsql forgets to do a SPI_push() before calling something that might try to use SPI re-entrantly. It should be perfectly deterministic and it definitely doesn't have anything to do with the states of other sessions. But we're going to need a test case to fix it. Tom, I'm not able to prepare a test case - the error is thrown exactly in two queries, but those queries can be executed without that error - there is no rule, when it will be thrown. When the error was thrown both queries cannot be executed (in the same connection of course, but in other connections they can be executed without problem). Before the error is thrown both queries were executed successfully (I'm logging all mod queries), but at some moment (unknown for me) the error is thrown and as I wrote those queries cannot be executed in current connection anymore - what is really strange is the fact that other queries (both selects and updates) can be executed in that connection and there some of those queries fires plpgsql triggers which updates db data (so SPI is used??). What can I do ? I don't want to do the downgrade :-( How can I track the moment, when plpgsql forgets to do SPI_push() ? I'm really appreciated for your help.

[GENERAL] filter duplicates by priority
Hello- I am trying to use DISTINCT ON to filter out *potential* duplicate values from a set of sub queries. There are certain cases where there can be repetitive part numbers that are priced differently. I'm trying to start with the full list, ordered by priority, and then remove any repeats that have a lesser priority. SELECT DISTINCT ON (part_number) * FROM ( SELECT part_number, priority FROM ... UNION ALL SELECT part_number, priority FROM ... UNION ALL SELECT part_number, priority FROM ... ) AS filter_duplicates ORDER BY priority,part_number The above statement does not work because if I ORDER BY priority,part_number then I have to DISTINCT ON (priority,part_number). But DISTINCT ON (priority, part_number) does not remove the repeated rows because the same part_number with a different priority becomes a distinct tuple. Any suggestions are appreciated. -- A more detailed explanation of my problem follows: I am working on an e-commerce system that has different lists of products which contain many of the same products, at different prices. When a user searches for a certain set of part numbers, I would like the resulting products (and prices) to come from one of the lists, according to the list's priority. Each user can have a different set of lists and priorities. Table: product_lists id | name | priority | user_id -+--+--+-- 5 | General List of Products| 2| 23 3 | Different List of Products | 3| 23 150 | Customer-Specific Products | 1| 23 Table: products product_list_id | part_number | price -+-+ 3| 92298A| 123.38 5| 92298A| 111.04 3| C39207| 78.38 150 | C39207| 67.93 Below is a simplified example of the structure of the query I am working with. I realize that in this case, I could re-factor all of this into one statement, but each sub-query in the real case has a more complex set of joins that determines the price. The pricing joins from one sub-query to the next vary, so a collection of sub-queries seemed to be a logical solution. Some part numbers are found in only one of the lists, while other part numbers are repeated across lists at different prices. This is what I would *like* to say: SELECT DISTINCT ON (part_number) * FROM ( SELECT product_list_id,part_number,price,priority FROM products, product_lists WHERE product_list_id=product_lists.id AND product_list_id=150 AND (part_number='92298A' OR part_number='C39207' OR part_number=...) UNION ALL SELECT product_list_id,part_number,price,priority FROM products, product_lists WHERE product_list_id= product_lists.id AND product_list_id=5 AND (part_number='92298A' OR part_number='C39207' OR part_number=...) UNION ALL SELECT product_list_id,part_number,price,priority FROM products, product_lists WHERE product_list_id= product_lists.id AND product_list_id=3 AND (part_number='92298A' OR part_number='C39207' OR part_number=...) ) AS filter_duplicates ORDER BY priority,part_number I need to ORDER BY priority so that, in the case of duplicates, the product from the desired list is returned first. Then the purpose of DISTINCT ON is to filter out any duplicate part numbers that have a lesser priority. But, the above statement fails because the DISTINCT ON expression must match the leftmost ORDER BY expression. However, inserting the priority into the DISTINCT ON expression means that all of the resulting tuples are unique, even though the part_number is the same. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general

Re: [GENERAL] prepared statements and DBD::Pg
-BEGIN PGP SIGNED MESSAGE-
Hash: RIPEMD160
It's perfectly valid (from the DBI's point of view) for prepare() to
return a prepared statement handle for an invalid statement.
It's not the job of prepare() to validate the SQL. It's a bonus if it
does, but the primary goal is to prepare as much as possible for
future execution.
There are *many* DBI drivers that can't/don't validate the SQL on
prepare. DBD::Oracle, for example, can but doesn't by default.
It defers the prepare until the first execute (or meta data is
requested) in order to reduce the number of round-trips.
Just to set the record straight on this thread, DBD::Pg also defers
actual preparation until needed (e.g. the first execute) and thus
will accept all prepare statements, regardless of what is inside
of them. It does this not only to save trips, but because bind_param
may be called betwixt the prepare and the execute.
This works fine with DBD::Pg:
$sth = $dbh-prepare('foobar');
However, this will then fail:
$sth-execute();
Thus, as pointed out elsewhere, the original report was not correct:
the error comes when execute() is called, not when prepare() is.
p.s. I'd be happy to see 'success with info' status returned if the
prepare() has to unexpectly fallback to client-side (and perhaps a dbh
counter incremeted). So users can tell when and how often it's happening
if they want to.
For DBD::Pg, this is not possible as prepare always works. Even if it didn't,
I think the fallback idea is not a good one, as we'd be potentially creating
many errors to have to rollback to (and creating a savepoint for every execute
attempt), and silently encouraging SQL that will fail when fed to Postgres
through any other interface.

Re: [GENERAL] [Q] single image Table across multiple PG servers
-BEGIN PGP SIGNED MESSAGE- Hash: RIPEMD160 The reason why I think the data will not fit into one database, is because I just do not have money for servers (everything is coming out of my small pocket) so I just want to deploy inexpensive computers but add them as I get more data to serve. I think you might be suffering from premature optimization. Or just wildly optimistic on your hardware needs. Postgres scales vertically extremely well, so I'd try out a single server and add sharding complexity only as a last resort. For scaling, you can use pgbouncer, spread the tables and indexes across different tablespaces, and other tricks.
