pg_upgrade 9.4 -> 9.5 with pg_trgm fails for me - Mailing list pgsql-general

Hi,

I have attempted a pg_upgrade on Debian using the Debian
wrapper scripts like so:

    pg_upgradecluster -v 9.5 9.4 main

(meaning to upgrade a cluster named "main" from 9.4 to 9.5)

which resulted in this:

    If pg_upgrade fails after this point, you must re-initdb the
    new cluster before continuing.

I do have pg_trgm installed in the 9.4 cluster for use with
the gnumed_vXX databases.

The relevant 9.5 Debian package containing pg_trgm for PG 9.5
(postgresql-contrib-9.5) is installed.

I am running this with a libpq compiled against PG 9.5.

For one thing - does it seem odd that the function would be
named "gtrgm_in" rather than "pgtrgm_in" ?

Anything else that seems off from the information given above?

What other information do I need to provide ?

(For what it's worth, I have also tried the --method=dump way
of using Debian's pg_upgradecluster which internally uses a
dump/restore cycle rather than calling pg_upgrade. That
failed due to ordering problems with table data vs table
constraints.)

Thanks a lot for any advice,
Karsten
