Cannot build INDEX on 12.2 (2021Q3 branch)

[Andrea Venturoli]

Hello.

Seems like sysutils/omnibackup looks for Postgres 9.5, which is gone.
Nothing fancy in /etc/make.conf.

# make index
Generating INDEX-12 - please wait..--- describe.accessibility ---

--- describe.x11-wm ---
make_index: /usr/ports/sysutils/omnibackup: no entry for 
/usr/ports/databases/postgresql95-client
 Done.

 bye
