Re: [ADMIN] Massive insert created 975 WAL segments.. what?
On 12 September 2012 01:10, Wells Oliver wellsoli...@gmail.com wrote: We were doing a test and inserted 1.5 million rows. In doing so, postgres created 974 WAL segments of 16MB apiece. The relevant configuration from my master's postgresql.conf: wal_level = hot_standby archive_mode = on archive_command = 'test ! -f /mnt/postgresql-logs/%f cp %p /mnt/postgresql-logs/%f' max_wal_senders = 3 wal_keep_segments = 16 So, now I have 16GB of WAL segments, 974 of them. Will postgresql clean this up? Will it remove these files? Will it create more with big inserts? What is the best way to manage this? These are transaction log files, created by database writes. They protect you if you crash and also allow replication/backup. These will be rotated every checkpoint, which by default is 5 minutes. So they'll be long gone by now. -- Simon Riggs http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training Services -- Sent via pgsql-admin mailing list (pgsql-admin@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
[ADMIN] pg_restore problem Found unexpected Block id
Hi , I am getting an error while restoring the Database Backup.

[ADMIN] Missing loadable libraries when running pg_upgrade 9.1 - 9.2
using Windows XP SP3 (32bit). When running pg_upgrade with the --check option I get the following error: Your installation references loadable libraries that are missing from the new installation. You can add these libraries to the new installation, or remove the functions using them from the old installation. A list of problem libraries is in the file: loadable_libraries.txt The content of loadable_libraries.txt is: Could not load library $libdir/targetinfo ERROR: could not access file $libdir/targetinfo: No such file or directory Could not load library $libdir/plugins/plugin_debugger ERROR: could not access file $libdir/plugins/plugin_debugger: No such file or directory And indeed there is no targetinfo.dll and no plugin_debugger.dll for 9.2 (there isn't even a plugins directory in lib) The relevant entries in the postgresql.conf for 9.1 are this: #shared_preload_libraries = '' # (change requires restart) #dynamic_library_path = '$libdir' #local_preload_libraries = '' So I'm a bit stumped on why pg_upgrade thinks that I'm using those libraries. Is there a way to find out which function (or extension?) is using those libraries in order to remove that dependency? The alternative would be to install those libraries, but the StackBuilder doesn't list them, and I didn't find anything in pgAdmin that would allow me to install them. They weren't installed with the installer and they are not part of the Windows ZIP distribution either. Any ideas?

What I ended up doing is to search through my pg_dump backups and I found the offending database. After removing the functions in question, everything went smoothly. Is there a better way to find those functions rather than doing a grep on the dump files?

PostgreSQL version 8.0 has been out of support overall for years, and out of support for Windows for years before that. http://archives.postgresql.org/pgsql-announce/2008-01/msg5.php http://www.postgresql.org/support/versioning/ Once you get past the immediate problems, it is extremely important that you update to a supported version and stay up-to-date with minor (bug-fix) releases. Regarding the immediate problem, your report could use a lot more detail. What steps have you taken to get to where you are now? Exactly what version of PostgreSQL is this (8.0.what?)? http://wiki.postgresql.org/wiki/Guide_to_reporting_problems Without knowing more, it's hard to give much advice. -Kevin -- Sent via pgsql-admin mailing list (pgsql-admin@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin

Well, pg_upgrade uses SQL queries to find those entries, so you could turn on logging and look at the SQL queries that look in the pg_proc table for such entries. -- Bruce Momjian br...@momjian.ushttp://momjian.us EnterpriseDB http://enterprisedb.com + It's impossible for everything to be true. + -- Sent via pgsql-admin mailing list (pgsql-admin@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
Re: [ADMIN] pg_upgrade with postgis
Hi - Thanks. As we installed using pg repos (yum) I don't think it will allow me to re-install postgis. Is it possible to specify a target cluster for a postgis install from repo or will it need to be installed from source? Thanks again.
