If you are upgrading a pre-PostgreSQL 9.2 cluster that uses a configuration-file-only directory, you must pass the real data directory location to pg_upgrade, and pass the configuration directory location to the server, e.g. -d /real-data-directory -o '-D /configuration-directory'. -o, --old-options=OPTIONS old cluster options to pass to the server -O, --new-options=OPTIONS new cluster options to pass to the server -- Bruce Momjian http://momjian.us EnterpriseDB http://enterprisedb.com + It's impossible for everything to be true. + -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs

I don't buy your argument. default 6201kB (64) updated 6967kB (128) on empty database - so it is 12% more per one database in our warehouses we have more than 10 relations per database and about 1000 databases per warehouse - so these number can be significantly higher second issue can be increasing memory allocations for system caches and some other place Regards Pavel > > > -- >Euler Taveira de Oliveira - Timbira http://www.timbira.com.br/ >PostgreSQL: Consultoria, Desenvolvimento, Suporte 24x7 e Treinamento -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs

[BUGS] w7 vs linux
Is pgsql faster on linux? Currently I've made an installation on W7 and the converted queries are about 3 times slower then on mssql. There's still some optimization to do tho...but the current results don't look to good.
Re: [BUGS] BUG #6722: Debugger broken?
Here is the two-lines howto for PG 9.2 for Windows. Uncomment and edit postgresql.conf: shared_preload_libraries = '$libdir/plugin_debugger' NB: in 9.2 the plugin_debugger.dll is not in the (non-existing) $libdi/plugins folder. Restart the server. Run CREATE EXTENSION pldbgapi; Cheers, A. -- View this message in context: http://postgresql.1045698.n5.nabble.com/BUG-6722-Debugger-broken-tp5715919p5733201.html Sent from the PostgreSQL - bugs mailing list archive at Nabble.com. -- Sent via pgsql-bugs mailing list (pgsql-bugs@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-bugs
Re: [BUGS] BUG #6722: Debugger broken?
Hi Could someone provide a short howto about installing debugger for PostgreSQL 9.1 and 9.2? Even a couple of lines would be very helpful. I did not find pldbgapi.sql in the share/contrib folder and the instructions that one finds online appear outdated. Thanks in advance.

Re: [BUGS] BUG #7685: last_value() not consistent throughout window partition
Sorry for wasting your time, I now see: If frame_end is omitted it defaults to CURRENT ROW. clearly in the documentation. I made the assumption that the default was UNBOUNDED PROCEDING/FOLLOWING which is now very obviously not the case. Again, sorry for not really taking the time to ensure this was in fact a bug. -W On Tue, Nov 20, 2012 at 10:47 AM, Tom Lane wrote: > w...@devauld.ca writes: > > -- The last_value(0 window function appears to be changing values > > -- mid window.
