[Pkg-dspam-misc] Missing information in the UPGRADING file.

[Philippe Le Brouster]

Hi,

I'm just doing some tests with dspam 3.9, especially an upgrade from
3.6.8 and it seems that the UPGRADING file is missing something for the
postgresql backend: between the version 3.8 and the version 3.9, there
is a new postgresql function and the UPGRADING file never talk about it.
The function is 'lookup_tokens(integer,integer,bigint[])' in the file
'src/tools.pgsql_drv/pgsql_objects.sql'. Perhaps it would be nice to
mention how to create this function (with the other intructions)?

Cheers,

Philippe.
