Hi all, As promised, this is a feedback on how things finally worked out OK for me. Method applied : 'pg_restore -l/-L' and based on 'filters' from 'http://rockfloat.com/blog/?id=42' meaning : Step 1. pg_restore -l my_db.tar | egrep -v '\|\||\@\@|stat\(|syn_|token_|tsvector|tsquery|tsdebug|ts_debug|tsearch|pg_ts_|dex_|lexize| parse|prsd_|_cur|snb_|spell_' >| /tmp/pg_restore.list Step 2. pg_restore -L /tmp/pg_restore.list -d my_db_name my_db.tar Regards, Chanh ----- Mail original ----- De: "chanh tran" <chanh.tran@xxxxxxx> À: "Tom Lane" <tgl@xxxxxxxxxxxxx> Cc: pgsql-admin@xxxxxxxxxxxxxx, "Robert Treat" <rob@xxxxxxxxxx> Envoyé: Lundi 22 Avril 2013 13:28:22 Objet: Re: Pb migrating database from Postgres 8.1 to 8.4 Also Thx to Robert :) ... ----- Mail original ----- De: "chanh tran" <chanh.tran@xxxxxxx> À: "Tom Lane" <tgl@xxxxxxxxxxxxx> Cc: pgsql-admin@xxxxxxxxxxxxxx, "Robert Treat" <rob@xxxxxxxxxx> Envoyé: Lundi 22 Avril 2013 13:27:29 Objet: Re: Pb migrating database from Postgres 8.1 to 8.4 Hi Tom, First of all, Big Thx for answering. Otherwise, thx also for all this hints. What about my case seems to be more related to the fact 'tsearch2' is already 'integrated' in 8.4 Whereas in 8.1, one has to have it 'imported' on purpose. All this leads to conflicts during 'restore' of my DB cf. http://rockfloat.com/blog/?id=42 I'll keep U posted on know how things work out via help from above link Regards, Chanh ----- Mail original ----- De: "Tom Lane" <tgl@xxxxxxxxxxxxx> À: "Robert Treat" <rob@xxxxxxxxxx> Cc: "chanh tran" <chanh.tran@xxxxxxx>, pgsql-admin@xxxxxxxxxxxxxx Envoyé: Vendredi 19 Avril 2013 18:09:40 Objet: Re: Pb migrating database from Postgres 8.1 to 8.4 Robert Treat <rob@xxxxxxxxxx> writes: > On Fri, Apr 19, 2013 at 10:19 AM, Tom Lane <tgl@xxxxxxxxxxxxx> wrote: >> chanh.tran@xxxxxxx writes: >>> I'm facing pbs trying to migrate my current database from Postgres 8.1 to 8.4. >>> pg_restore: [archiver (db)] could not execute query: ERROR: could not find function "gtsvector_in" in file "/usr/lib64/pgsql/tsearch2.so" >> Looks like you're missing the shared library that underlies tsearch2. >> The other errors seem to be consequences of this one. > It might be cleaner to try and remove the tsearch bits from your > schema dump and get a fresh install of tsearch by itself before > loading in your own schema. Actually, on second look, I think this is expected behavior when trying to update from pre-8.3 text search --- that whole conversion was none too clean. Note the warning in the tsearch2 module documentation about 3. Load the dump data. There will be quite a few errors reported due to failure to recreate the original tsearch2 objects. These errors can be ignored, but this means you cannot restore the dump in a single transaction (eg, you cannot use pg_restore's -1 switch). If you weren't actually using the tsearch2 features before, you might be best advised to uninstall tsearch2 from the old database before you convert. If you were, please read the documentation about text search conversion carefully --- both http://www.postgresql.org/docs/8.4/static/textsearch-migration.html and the contrib/tsearch2 page. regards, tom lane -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
