Hi!
I currently testing the upgrade of our 8.3 databases to 9.0.
In some of those restored databases to_tsquery is throwing an error:
magazine=# SELECT to_tsquery('simple','plants');
ERROR: invalid input syntax for type oid: "simple"
LINE 1: SELECT to_tsquery('simple','plants');
In other databases, it's working fine; the same applies to newly created
databases on this cluster.
Now my Google-fu seems to be somewhat lacking because I couldn't find
anything on this precise error condition.
I dumped the old databases using
su postgres -c "time /opt/pgsql/bin/pg_dump -s mydb | gzip
>~/mydb-schema.sql.`date -I`.gz"
su postgres -c "time /opt/pgsql/bin/pg_dump -a mydb -Fc
>~/mydb-data.`date -I`.pg"
Source version() is PostgreSQL 8.3.7 on x86_64-unknown-linux-gnu,
compiled by GCC gcc (Debian 4.3.2-1.1) 4.3.2
Target version() is PostgreSQL 9.0.1 on x86_64-unknown-linux-gnu,
compiled by GCC gcc (Debian 4.4.5-4) 4.4.5, 64-bit
I suspect it has to do with the Tsearch2-compatibility modules from
contrib - these were compiled and installed to a couple of databases on
the old cluster; I haven't yet compiled and installed them to the new
databases as I'd like to get rid of some dead weight in the migration
process.
http://www.postgresql.org/docs/9.0/static/tsearch2.html doesn't
elaborate further on how to get rid of the replacement tsearch2 module
stuff.
Any ideas on how to resolve this issue?
Kind regards
Markus
